[Aditya Nandakumar via Phabricator via llvm-commits]

aditya_nandakumar updated this revision to Diff 181647.
aditya_nandakumar added a comment.

Updated to add a CSEConfig class that describes what instructions should be CSEd.
Additionally, updated IRTranslator and Legalizer to only perform CSE for G_CONSTANTS for -O0.
