[PATCH] D34048: [PowerPC] Eliminate compares - add i32 sext/zext handling for SETLE/SETGE

[Nemanja Ivanovic via Phabricator via llvm-commits]

nemanjai created this revision.

This patch adds a bit more of the infrastructure for doing comparisons in GPR's. It provides GE/LE patterns for i32's as well as the computation for GE/LE comparisons against zero for both i32 and i64.

Posting this for review since it's not just a patch that adds patterns - there's a bit of additional infrastructure.
