[PATCH] D31851: [PowerPC] Eliminate compares - add handling for logical operations without the use of condition registers

[Nemanja Ivanovic via Phabricator via llvm-commits]

nemanjai added a comment.

This revision does away with the Boolean parameter to `getLogicOpInGPR` and adds the logic to extract the CR result at the only call of that function that needs it.
Furthermore, this patch eliminates bitwise negations if they're produced by instructions that have a record-form.
