[PATCH] D130956: [X86][MC] Always emit `rep` prefix for `bsf`

[Kan Shengchen via Phabricator via llvm-commits]

skan added a comment.

I believe Linus's suggestion is adding a prefix to BSF rather than changing the encoding.
Maybe you can consider implementing it in `X86MCInstLower::Lower` by using `Flags` of `MCInst`.
