[PATCH] D40554: [PowerPC] Fix bugs in sign-/zero-extension elimination

[Stefan Pintilie via Phabricator via llvm-commits]

stefanp updated this revision to Diff 393264.
stefanp added a comment.

Found that POPCNTW instruction does not ensure that the upper 32 bits
are cleared. As a result I have removed it from the list.
