Research direction
Start by examining the cpufeatures implementation for existing x86 target features and compare it with the linked Rust std_detect source. Add recognition for fsrm and ermsb, then verify that the feature detection behavior and any relevant tests cover both names.

Description
fsrm: Fast Short REP MOVSB
ermsb: Enhanced REP MOVSB/STOSB
rust-lang already appears to include ermsb https://github.com/rust-lang/rust/blob/035b01b794602d5861daa43ac792f372f8981ed7/library/std_detect/src/detect/arch/x86.rs#L276
