x86: Error on -fcf-protection with incompatible target
-fcf-protection with CF_BRANCH inserts ENDBR32 at function entries.
ENDBR32 is NOP only on 64-bit processors and 32-bit TARGET_CMOV
processors. Issue an error for -fcf-protection with CF_BRANCH when
compiling for 32-bit non-TARGET_CMOV targets.
