[PATCH] D58595: [TableGen][SelectionDAG][X86] Add specific isel matchers for immAllZerosV/immAllOnesV. Remove bitcasts from X86 patterns that are no longer necessary.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.

+      else if (isImmAllOnesAllZerosMatch(Child))
+        Size += 4;
       else if (!Child->getPredicateCalls().empty())
----------------
Add a comment describing the size?
