initial merge of GCC 10.3.0.

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.

import GCC 5.3.0. see these urls for details which are too large to

import GCC 5.3.0. see these urls for details which are too large to
include here:
http://gcc.gnu.org/gcc-4.9/changes.html
http://gcc.gnu.org/gcc-5/changes.html
(note that GCC 5.x is a release stream like GCC 4.9.x, 4.8.x, etc.)
the main issues we will have are:
The default mode for C is now -std=gnu11 instead of -std=gnu89.
ARM:
The deprecated option -mwords-little-endian has been removed.
The options -mapcs, -mapcs-frame, -mtpcs-frame and -mtpcs-leaf-frame
which are only applicable to the old ABI have been deprecated.
MIPS:
The o32 ABI has been modified and extended. The o32 64-bit
floating-point register support is now obsolete and has been removed.
It has been replaced by three ABI extensions FPXX, FP64A, and FP64.
The meaning of the -mfp64 command-line option has changed. It is now
used to enable the FP64A and FP64 ABI extensions.
