Now that we check for valid sub-insns in parallel insns, we can
enable the tests that explicitly validate those code paths.

Now that we keep track of the exact parallel insn slot we're in, we can
make sure that the current insn being decoded is valid for that slot.
This brings us much closer to the hardware in flagging invalid parallel
insn combinations.

Some insns need to know which slot they're in to determine whether they
are valid. So add an enum for each slot, and check that rather than the
overall insn len. This makes tracking things in the code much clearer.
However, this code is functionally the same, so a follow up patch will
leverage this more to properly flag invalid parallel insn combos.

The amod1 helper includes a leading space so it can expand into the empty
string when need be, which means the caller need not add spacing itself.

Parallel insns can only do one 32bit, then two 16bits. So if we see
a 2nd 32bit insn after the first 32bit in a parallel insn, abort.

Similar to logic in the cris exp, attempt a simple compile and if it fails
(presumably due to the compiler being broken), skip all the related tests.
Fortunately, most tests (~600 out of ~800) are pure assembly, so people should
still get pretty good coverage.

Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

The sim code gets the logic for SIM_AC_OPTION_WARNINGS from gdb, but
it hasn't been updated in a good long while. Sync with the latest
gdb code.
There is a sim specific change in here: we disable -Werror for now.
This is because all sim code atm contains warnings. Will probably
have to slowly add a white list of targets which can tolerate this
until everyone is updated.

This isn't entirely correct in that it assumes the signal numbering of

The 32bit allopcodes test had quite a bit of optimization added to it
so that it ran in a reasonable amount of time out of uncached memory.
Port those changes over to the 16bit test so the two share common code.

AIX 7.1 defines st_pad[123] to st_[amc]tim.tv_pad, respectively,
breaking declaration of st_pad[123] members in struct solaris_stat.
Undefine them as this is no less terrible than other solutions (like
renaming the fields and losing the binding to Solaris' names).

The cr16 libgloss port does not define these syscall numbers, so trying
to use them results in build failures [1]. The cr16 code already uses
ifdefs around a bunch of syscalls, so extend that style to cover the
ones that are currently missing. Now we can at least compile.

Building the sim on a sparc-solaris 2.8 machine fails when configured

The same thing happens with the version of bash that we got from
Sun as well (which is very old: 2.03.0(1)-release).
The problems comes from the fact that both shells are buggy, and
reject the following script:
for hw in ; do
[...]
done
The above is what sim/common/Makefile.in tries to execute when
generating hw-config.h.
In order to allow users to build out of the box on these machines,
this patch works around this bug. It does rely on the fact that
none of the tokens in SIM_HW contain whitespaces.
sim/common/ChangeLog:
* Make-common.in (hw-config.h): Work around bug in Solaris 2.8
system bourne shell.
Parsing target addresses is hard if not generally useless, so use the new
cb_get_string function to lookup the associated strings as well. Now the
trace output is quickly useful instead of just marginally so.
