elf: Add -z unique-symbol to avoid duplicated local symbol names
The symbol string table in the .symtab section is optional and cosmetic.
The contents of the .symtab section have no impact on run-time execution.
The symbol names in the symbol string table help distinguish addresses at
different locations. Add a linker option, -z unique-symbol, to avoid
duplicated local symbol names in the symbol string table.
This feature was well received by the livepatch maintainers. It not only
solves the duplicated local symbol name problem, but also would allow
livepatch to more precisely locate duplicate symbols in general for
patching.

Add bfloat16 support for AVX512 register view.
This adds support for the bfloat16 datatype, which can be seen as a short
version of FP32, skipping the least significant 16 bits of the mantissa.
Since the datatype is currently only supported by the AVX512 registers,
the printing of bfloat16 values is only supported for xmm, ymm and zmm

gas: Don't error when .debug_line already exists, unless .loc was used
When -g was used to generate DWARF gas would error out when a .debug_line
already exists. But when a .debug_info section already exists it would
simply skip generating one without warning or error. Do the same for
.debug_line. It is only an error when the user explicitly uses .loc
directives and also generates the .debug_line table itself.
The tests are unfortunately arch specific because the line table is only
generated when actual instructions have been emitted. Use i386 because
that is probably the most used architecture. Before this patch the new
dwarf-line-2 testcase would fail, with this patch it succeeds (and doesn't
try to add its own line table).

Allow plugin syms to mark as-needed shared libs needed
when removing unused IR symbol references, ld didn't add unnecessary
DT_NEEDED libraries which may lead to undefined symbol reference in a
--as-needed library when the symbol is defined in a prior --as-needed
library and there is no reference in relocatable inputs. This behavior
is desirable since it ensures that both lazy and non-lazy bindings work
the same way. The problem is with --as-needed libraries, which happens
with and without LTO. Now, the linker may add many unnecessary DT_NEEDED
libraries for IR inputs.

387d0773f3 changed the D demangler, with the following
commit log:
libiberty: Add support for `in' and `in ref' storage classes.
The storage class `in' is now a first-class citizen with its own mangle
symbol, of which also permits `in ref'. Previously, `in' was an alias
to `const [scope]', which is a type constructor.
The mangle symbol repurposed for this is `I', which was originally used
by identifier types. However, while TypeIdentifier is part of the
grammar, it must be resolved to some other entity during the semantic
passes, and so shouldn't appear anywhere in the mangled name.
Old tests that are now no longer valid have been removed.

bfin-elf complains about not supporting copy relocs, but it's quite
silly to want a copy reloc for common symbols, so leave the fail
there. mn10300-elf and score-elf both fail the test with "PHDR
segment not covered by LOAD segment". Other tests fail similarly so
one more doesn't hurt. The failure is a consequence of supporting
dynamic objects but setting EMBEDDED in ld scripts.

Fix latent bug in ada-lang.c:remove_extra_symbols
I believe ada-lang.c:remove_extra_symbols has a latent bug. This
function loops over a vector of symbols, removing duplicates according
to some criteria.
At the end of the loop it does:
if (remove_p)
syms->erase (syms->begin () + i);
i += 1;
However, this seems wrong to me -- when removing the i'th element,
this code still increments "i", thus skipping an element.
At first I thought this was a regression from the patches to remove
cleanups from ada-lang.c (this was when std::vector was introduced);
but I found that instead the bug seems to be older:
if (remove_p)
{
for (j = i + 1; j < nsyms; j += 1)
syms[j - 1] = syms[j];
nsyms -= 1;
}
i += 1;
No test, as I don't know how to write one.
As this is Ada-specific, and was already reviewed internally by Joel,
I am checking it in.

Do not adjust mtime timezone on Windows
PR win32/25302 notes that gdb will crash when trying to "run" even a
simple program on Windows. The essential bug here is that the BFD
cache can easily be corrupted -- I have sent a separate patch for
that.
The particular reason that the cache is corrupted on Windows is that
gnulib overrides "stat" to make it do timezone adjustment -- but BFD
does not use this version of stat. The difference here triggers the
latent cache bug, but can also cause other bugs as well; in particular
it can cause spurious warnings about source files being newer.
This patch simply removes the stat override on mingw, making gnulib
and BFD agree.
I tested this by backing out the local AdaCore changes to work around
this bug and then verifying that I could reproduce it. Then, I
applied this patch and verified that "run" works again.

Avoid hash table corruption in gdb_bfd.c
gdb caches BFDs that come from ordinary files. This code turns out to
have a bug where the hash table can become corrupted, causing gdb to
crash.
When gdb_bfd_open opens the BFD, it uses fstat to get the BFD's mtime.
This is used when inserting the entry into gdb_bfd_cache. Then, the
function creates the gdb_bfd_data object as a side effect of calling
new_reference. This object is used when finding objects in the hash
table, and its constructor uses bfd_get_mtime. So, if the file
changes between the time the BFD is put into the cache and the time
that this object is created, the hash table will be incorrect. When
the BFD is later deleted, its entry in the hash table will not be
found, and at this point the hash table will point to invalid memory.
This patch fixes the bug by ensuring that the mtime, and other
relevant attributes comgin from stat, that are used for insertion are
also used when creating the gdb_bfd_data.
This obsoletes an earlier patch that had split this into two parts
(surrounding a patch to use bfd_stat more consistently). This version
merges the two patches, in the interest of correctness.

MSP430: Support relocations for subtract expressions in .uleb128 directives
Link-time relaxations of branches are common for MSP430, given that GCC
can generate pessimal branch instructions, and the
-mcode-region=either/-mdata-region=either options to shuffle sections
can further change the type of branch instruction required.
These relaxations can result in invalid code when .uleb128
directives, used in the .gcc_except_table section, are used to calculate
the distance between two labels. A value for the .uleb128 directive is
calculated at assembly-time, and can't be updated at link-time, even if
relaxation causes the distance between the labels to change.
This patch adds relocations for subtract expressions in .uleb128
directives, to allow the linker to re-calculate the value of these
expressions after relaxation has been performed.

sim: better handle builds of primary targets lacking sims
When building with a primary target that doesn't feature a simulator,
one would expect for nothing to be done in sim/. However, a
$(top_builddir)/sim/testsuite directory is created, with a Makefile
containing a rule like:
check-DEJAGNU: site.exp
echo "Dejagnu-checking in `pwd` directory ..."
rootme=`pwd`; export rootme; echo rootme = $$rootme; \
srcdir=`cd ${srcdir}; pwd`; export srcdir ; echo srcdir = $$srcdir; \
EXPECT=${EXPECT} ; export EXPECT ; echo EXPECT = $$EXPECT; \
if [ -f $$rootme/../../expect/expect ]; then \
TCL_LIBRARY=`cd $$srcdir/../../tcl/library && pwd`; \
export TCL_LIBRARY; \
fi; \
echo TCL_LIBRARY = $$TCL_LIBRARY; \
runtest=$(RUNTEST); echo runtest = $$runtest; \
if $(SHELL) -c "$$runtest --version" > /dev/null 2>&1; then \
$$runtest $(RUNTESTFLAGS); \
else echo "WARNING: could not find \`runtest'" 1>&2; :;\
fi
Consequently, when `make check' recurses into sim/testsuite, the above
rule is executed. Until now, the desired effect (of doing nothing)
was achieved because `runtest --version' fails due to a malformed
site.exp being generated in objdir: it is malformed because the
primary target doesn't configure a $sim_arch. i.e. this was doing the
right thing just by chance.
However, the git version of dejagnu seems to have changed in a way
runtest doesn't try to load site.exp when it gets --version. The net
effect is that the rule above tries to actually run the tests, failing
miserably.
This little patch makes sim/configure to not recurse into
sim/testsuite if the primary target didn't configure a simulator.
Tested with:
- A simulator target (bpf-unkonwn-none).
- A simulator-less target (x86_64-linux-gnu).
- A simulator-less target and --build-targets=all.

These children are weird, but even weirder when a variant type is
involved, because only the non-varying parts of the type are
displayed. This behavior conflicts a bit with my ongoing quest to
move the Ada code to use DWARF rather than gnat encodings, in that
