[PATCH] D137934: [InstCombine] Fold extractelt with select of constants

[Thomas Symalla via Phabricator via llvm-commits]

tsymalla updated this revision to Diff 475413.
tsymalla added a comment.

Removed the whole custom implementation as InstCombine is already able 
to do the constant folding, but the Visitor for extractelement needs an 
additional check to prevent folding the constants into select operands
when the select uses a condition vector.
