[PATCH] D48606: [X86] Use bts/btr/btc for single bit set/clear/complement of a variable bit position

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

1. No tests for 16-bit case.
2. Pattern with memory operands unhandled
3. Pattern with immediates not handled.

(i can follow-up with that, if wanted, mostly have the tests anyway)
