Update to gcc 9.2.0
Forward ported patches from GCC 8.3.0 to 9.2.0, refreshed to match
current sources.
In patch 0012-crystax.patch, removed changing sysv4.h header file for
rs6000, since it no longer defines LINK_EH_SPEC.
Removed the following patches because they are part of upstream:
- 0018-ARC-Add-multilib-support-for-linux-targets.patch
- 0020-ARM-fix-cmse.patch
- 0021-arm-Make-arm_cmse.h-C99-compatible.patch
- 0022-ARC-Update-fma-expansions.patch
Renamed 0019-isl-0.20.patch => 0018-isl-0.20.patch.
