Most of the patches are copied over from GCC 8.3.
The following patches are backported from the GCC 9.X development branch:
toolchain/gcc/patches/9.1.0/970-recompute-dom-fast-queries-before-vn.patch
toolchain/gcc/patches/9.1.0/975-g++-ICE-with-generic-lambda.patch
The specs file changed with gcc 9, now it contains "%@{L*}" instead of
"%{L*}" in older GCC versions.

MIPS16 functions have a static assembler prologue which clobbers
|
|
registers v0 and v1. Add these register clobbers to function call
|
|
instructions.
