Stuart Hastings 7b7c102f2c Add support for x86 CMPEQSS and friends. These instructions do a 
floating-point comparison, generate a mask of 0s or 1s, and generally
DTRT with NaNs.  Only profitable when the user wants a materialized 0
or 1 at runtime.  rdar://problem/5993888

Rafael Espindola d11311f291 Fix PR9127 by reversing the operands even if they have more then one use. 
Reversing the operands allows us to fold, but doesn't force us to. Also, at
this point the DAG is still being optimized, so the check for hasOneUse is not
very precise.
