mesa: add support for CET to x86/x86-64 asm files.
Control-flow enforcement technology is a new instructions on x86 processors to denote where indirect jumps can land. Gcc auto adds the instruction (which encodes as a NOP on older CPUs) to entrypoints but assembler files need manual adding. This adds it to all the entry points in the mesa x86/x86-64 assembler files. This will only happen if mesa is built with the -fcf-protection flag to gcc as some distros are wanting to do. Acked-by: Eric Anholt <[email protected]>
