sim: introduce {COMPILE,LINK}_FOR_BUILD
These use the same pattern as seen in the opcodes/ dir and in automake
in general (ish). This helps simplify the boilerplate for building and
linking build-time code, and fixes some inconsistency in flag usage.
For rules that were compiling+linking in a single step, split them into
separate steps so we can apply the correct set of options. This matches
automake behavior too.

Use RAII to set the per-thread SIGSEGV handler

aix: implement TLS relocation for gas and ld
Add support for TLS in XCOFF. Amongst the things done by this commit:
- Update XCOFF auxialiary header to match new version and allow TLS
sections.
- Add TLS sections (.tdata and .tbss) support in gas and ld.
- Add support for the TLS relocations in gas and ld.
Two different types BFD_RELOC are created for PPC and PPC64 as
the size is a pointer, thus distinct in 32 or 64bit.
The addresses given by ld to .tdata and .tbss is a bit special. In
XCOFF, these addresses are actually offsets from the TLS pointer
computed at runtime. AIX assembly and linker does the same. In
top of that, the .tdata must be before .data (this is mandatory for AIX
loader). Thus, the aix ld script is recomputing "." before .data to restore
its original value. There might be a simpler way, but this one is working.
Optimisation linked to TLS relocations aren't yet implemented.

RISC-V: Improve multiple relax passes problem.
According to the commit
abd20cb637008da9d32018b4b03973e119388a0a, an
intersting thing is that - the more relax passes, the more chances of
relaxations are reduced [1]. Originally, we set the boolean `again`
to TRUE once the code is actually deleted, and then we run the relaxations
repeatedly if `again` is still TRUE. But `again` only works for the
relax pass itself, and won't affect others. That is - we can not use
`again` to re-run the relax pass when we already enter into the following
passes (can not run the relax passes backwards). Besides, we must seperate
the PCREL relaxations into two relax passes for some reasons [2], it make
us lose some relax opportunities.
This patch try to fix the problem, and the basic idea was come from Jim
Wilson - we use a new boolean, restart_relax, to determine if we need to
run the whole relax passes again from 0 to 2. Once we have deleted the
code between relax pass 0 to 2, the restart_relax will be set to TRUE,
we should run the whole relaxations again to give them more chances to
shorten the code. We will only enter into the relax pass 3 when the
restart_relax is FALSE, since we can't relax anything else once we start
to handle the alignments.
I have passed the gcc/binutils regressions by riscv-gnu-toolchain, and
looks fine for now.

bfd: don't silently wrap or truncate PE image section RVAs
In PE images section addresses get expressed as addresses relative to
the image base. Therefore the VA of a section must be no less than the
image base, and after subtraction of the image base the resulting value
should fit in 32 bits. (The issue is particularly obvious to notice when
sections, perhaps because of ELF assumptions, get placed at VA 0 by
default. Debugging info sections as well as .comment, when input files
are ELF, are a good example. All such sections need proper mentioning in
the linker script to avoid this warning.)
There are a number of test cases which previously produced bogus images,
yet still declared the test a success. Like done for other tests
already, force a zero image base for these. This then also allows (and
requires) dropping again xfail-s which
39a7b38fac0e ("Fix linker tests
to work with 16-bit targets") had added to ld-scripts/default-script*.d
(originally as skip-s). This also depends on similar adjustments to

Remove union exp_element
This removes union exp_element functions that either create such

exp_elements. A couple of language_defn methods are also removed, as
they are obsolete.
Note that this patch also removes the print_expression code. The only
in-tree caller of this was from dump_prefix_expression, which is only
called when expression debugging is enabled. Implementing this would
involve a fair amount of code, and it seems to me that prefix dumping
is preferable anyway, as it is unambiguous. So, I have not
reimplemented this feature.

leaks that would result if raw pointers were used in the parsers, at
the cost of parser productions not being type-safe (they can't

Implement Ada assignment
Assignment is the most complicated Ada expression, because
implementing aggregate assignment involves several specialized
opcodes.
This patch does this implementation by introducing new abstract
classes that are used to represent the various parts of aggregate
assignment. This makes the code somewhat cleaner, and, by avoiding
the over-use of 'operation' subclasses, avoids the need for dissection
using dynamic_cast (though a few are still needed here).
I believe this patch fixes a latent bug in the handling of
aggregate_assign_from_choices. That code does:
if (op == OP_DISCRETE_RANGE)
{
choice_pos += 1;
lower = value_as_long (ada_evaluate_subexp (NULL, exp, pos,
EVAL_NORMAL));
upper = value_as_long (ada_evaluate_subexp (NULL, exp, pos,

'pos'.

Implement Ada resolution
Ada has a parser post-pass that implements "resolution". This process
replaces some opcodes with function calls. For example, a "+"
operation might be replaced with a call to the appropriate overloaded
function.
This differs from the approach taken for the same problem in C++.
However, in this series I chose not to try to make changes outside of
rewrite the expression data structure. So, resolution remains.
The new approach to resolution is to introduce an interface class,
that some concrete operations implement. Then, the Ada code will use
this to resolve the expression tree. Because new-style expressions
are built as ordinary objects, and don't require rewriting the data
structure in place, in the new code this processing will be done in
the parser. By the end of the series, some special cases in this area
that exist only for Ada will be removed.

Implement function calls for Ada
This implements function calls for Ada. This takes a different
approach than that used for other languages, primarily because Ada
requires special treatment generally. The "ordinary" special case for
just the callee didn't really apply neatly here; there's only one case
in Ada needing special callee treatment.
