merge GCC 12.4.0.

branches: 1.16.2;
initial merge of GCC 12.3.0.

this doesn't include any of the changes to the .c -> .cc files renamed,
and reverts our local changes to the vax port and libsanitizer subdir.
vax GCC was rewritten and our local fixes no longer are relevant, and
the new libsanitizer is more updated than our old one, and merging via
gcc10->gcc12 is not really possible.

unfortunately, our local changes to libsanitizer that aren't related
to the general update of those sources (ie, the netbsd code) will need
to be re-checked and perhaps re-ported.

merge GCC 10.5.0.

branches: 1.14.2;
merge GCC 10.4.0.

initial merge of GCC 10.3.0.

these three files are not yet finished merging:

gcc/config/rs6000/rs6000.c
libsanitizer/lsan/lsan_allocator.h
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.h

our current GCC 9 sanitizers are newer than GCC 10's still, so that
may take a little to untease, so it's probable that more than
these 2 will need more changes.

rs6000.c has some changes related to ABI and supported functionality
that need to be merged forward.

merge GCC 9.3.0.

merge GCC 8.4.0.

merge GCC 8.3.0 pass 1. will not compile yet. thare are still
about 25 files with merge issues.

other changes merged easily.

branches: 1.5.8;
merge GCC 5.3. round 1. this probably won't work :-)

the updating we'll need i think already.
