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.

add the spectre mitigation options for x86:
-mindirect-branch=<choice> -mfunction-return=<choice> -mindirect-branch-register
the values for 'choice' are "keep" (default, existing behaviour), "thunk", "thunk-inline", and "thunk-extern".
as taken from the Debian port of these changes in their debian:gcc-6_6.3.0-18+deb9u1.diff. i've also included the doc updates that are missing from debian from gcc itself.
i've tested both i386 and amd64 fairly heavily with these options enabled in both kernels and userland, atf runs and hundreds of package builds.

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 It has been replaced by three ABI extensions FPXX, FP64A, and FP64.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.

GCC now uses C++ as its implementation language. This means that to build GCC from sources, you will need a C++ compiler that understands C++ 2003 DWARF4 is now the default when generating DWARF debug information A new general optimization level, -Og, has been introduced A new option -ftree-partial-pre was added The option -fconserve-space has been removed The command-line options -fipa-struct-reorg and -fipa-matrix-reorg have been removed Interprocedural and Link-time optimization improvements AddressSanitizer, a fast memory error detector, has been added [*2] A new -Wsizeof-pointer-memaccess warning has been added G++ now supports a -std=c++1y option for experimentation with features proposed for the next revision of the standard, expected around 2014 Improved experimental support for the new ISO C++ standard, C++11 A new port has been added to support AArch64 Updates for ARM, x86, MIPS, PPC/PPC64, SH, SPARC, TILE*
