[PATCH] D21144: [X86]: Quit promoting 8 and 16 bit compares to 32 bit.

[Kevin B. Smith via llvm-commits]

kbsmith1 updated this revision to Diff 60244.
kbsmith1 added a comment.

Updated changes so this will continue to promote 16 bit compares to 32 bits if one of the compare
operands is a constant.  This addresses Eli Friedman's comment.
