gdb/riscv: Provide non-DWARF stack unwinder
Collects information during the prologue scan and uses this to unwind

PR23595, simple objcopy of executable failure for msp430-elf
VMA of the first section in the segment containing the ELF file header
(and possibly section headers too) can't be used to reliably find the
size of the headers plus padding. What's really needed is sh_offset
of the first section assuming it has contents (vma does have a
relationship to sh_offset, but is only guaranteed in demand paged
executables).
If the first section is SHT_NOBITS and it hasn't been converted to
have file contents by the existence of a following SHT_PROGBITS
section in the same segment, the sh_offset value also isn't reliable.

gdb/riscv: remove extra caching of misa register
The RISC-V had a mechanism in place to cache the contents of the misa
register per-inferior, the original intention behind this was to
reduce the number of times the misa register had to be read (as the
contents should be constant), but it was pointed out on the mailing
list[1] that the register cache will mean the register is only
accessed once each time GDB stops, and any additional caching is
probably just unneeded extra complexity.
As such, until it can be shown that there's a real need for additional
caching, this commit removes all of the additional caching of the misa
register, and just accesses the misa register like a normal register.

gdb: Ensure compiler doesn't optimise variable out in test
In the test gdb.base/funcargs.exp, there's this function:
void recurse (SVAL a, int depth)
{
a.s = a.i = a.l = --depth;
if (depth == 0)
hitbottom ();
else
recurse (a, depth);
}
The test script places a breakpoint in hitbottom, and runs the
executable which calls recurse with an initial depth of 4.
When GDB hits the breakpoint in hitbottom the testscript performs a
backtrace, and examines 'a' at each level.
The problem is that 'a' is not live after either the call to
'hitbottom' or the call to 'recurse', and as a result the test fails.
In the particular case I was looking at GCC for RISC-V 32-bit, the
variable 'a' is on the stack and GCC selects the register $ra (the
return address register) to hold the pointer to 'a'. This is fine,
because, by the time the $ra register is needed to hold a return
address (calling hitbottom or recurse) then 'a' is dead.
In this patch I propose that a use of 'a' is added after the calls to
hitbottom and recurse, this should cause the compiler to keep 'a'
around, which should ensure GDB can find it.

C++ compile support
This patch adds *basic* support for C++ to the compile feature. It does
most simple type conversions, including everything that C compile does and
your basic "with-classes" type of C++.
I've written a new compile-support.exp support file which adds a new test
facility for automating and simplifying "compile print" vs "compile code"
testing. See testsuite/lib/compile-support.exp and CompileExpression
for more on that. The tests use this facility extensively.
This initial support has several glaring omissions:
- No template support at all
I have follow-on patches for this, but they add much complexity
to this "basic" support. Consequently, they will be submitted separately.
- Cannot print functions
The code template needs tweaking, and I simply haven't gotten to it yet.
- So-called "special function" support is not included
Using constructors, destructors, operators, etc will not work. I have
follow-on patches for that, but they require some work because of the
recent churn in symbol searching.
- There are several test suite references to "compile/1234" bugs.
I will file bugs and update the test suite's bug references before pushing
these patches.
The test suite started as a copy of the original C-language support, but
I have written tests to exercise the basic functionality of the plug-in.
I've added a new option for outputting debug messages for C++ type-conversion
("debug compile-cplus-types").

Looking into this, I found two things.
First, in struct xlate_exception, it is better to have "them" be of
type DWORD, as that's the type actually in use.
Second, struct xlate_exception and xlate are not used in this file,
because the code in windows_nat_target::resume is #if'd out.
This patch changes the type of "them", but also similarly #if's out
this object.
In order to avoid a narrowing warning from the -1 entry, at Pedro's
suggestion I have removed this and changed windows_nat_target::resume
to use ranged for.
Tested by rebuilding using the mingw toolchain on x86-64 Fedora 28. I
also tested it by temporarily removing the "#if 0"s and rebuilding.

sparc/leon: add support for partial write psr instruction
Partial write %PSR (PWRPSR) is a SPARC V8e option that allows the WRPSR
instruction to only affect the %PSR.ET field. When available it is enabled
by setting the rd field of the WRPSR instruction to a value other than 0.
For Leon processors with support for partial write %PSR (currently GR740
and GR716) the rd value must be 1.

Fix riscv-linux native gdb build failure.
The linux kernel uses NT_PRFPREG. Glibc before BZ 14890 defines NT_FPREGSET.
After it defines both. Avoid glibc version dependency by using the gdb header
file instead of the glibc header file, and the macro name that gdb defines
which is NT_FPREGSET.

Update gnulib to current upstream master
It has been a while since we don't update our gnulib copy against
their upstream master branch, so I thought I'd propose this patch. It
also fixes (at least) one bug reported against GDB:
https://sourceware.org/bugzilla/show_bug.cgi?id=23558
The problem reported there is about the replacement of 'getcwd' when
cross-compiling GDB. With our current gnulib copy, the mechanism for
deciding whether to use the system's 'getcwd' or gnulib's version is
too simplistic and pessimistic, so when cross-compiling we always end
up using gnulib's version, which has a limitation: it cannot handle
the situation when the parent directory doesn't have read permissions.
This has been reported against upstream gnulib and the fix has been
pushed here:
https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=
a96d2e67052c879b1bcc5bc461722beac75fc372
I regtested this patch on Fedora 28 x86-64, and there were no
regressions.
OK?

GDB should read an empty list of command once, but it reads
it for each breakpoint, as an empty list of command is NULL,

MI: Fix printing of frame architecture with Python frame filters enabled
Commit
6d52907e226a (MI: Print frame architecture when printing frames
on an MI channel) added frame's architecture to MI frame output. However
the frame architecture was not correctly printed in the output of
"-stack-list-frames" with frame filters enabled (via "-enable-frame-filters").
This was because with frame filters enabled, the actual frame printing is
done in "py_print_frame" rather than "print_frame". This issue is now fixed.

702d16713 broke expressions using CONSTANT(COMMONPAGESIZE)

optional fields were evaluated at script parse time and the patch in
