[PATCH] D120219: [X86] Canonicalize SGT/UGT compares with constants for JCC to use SGE/UGE to reduce the number of EFLAGs reads.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

AMD targets tend to split the flags register into subregisters, so reading fewer flags often means we avoid multiple reads.
