[PowerPC] Eliminate compares - add i64 sext/zext handling for SETLT/SETGT As mentioned in https://reviews.llvm.org/D33718, this simply adds another pattern to the compare elimination sequence and is committed without a differential review. llvm-svn: 314106

[PowerPC] Recommit r314244 with refactoring and off by default This re-commits everything that was pulled in r314244. The transformation is off by default (patch to enable it to follow). The code is refactored to have a single entry-point and provide fine-grained control over patterns that it selects. This patch also fixes the bugs in the original code. Everything that failed with the original patch has been re-tested with this patch (with the transformation turned on). So the patch to turn this on is soon to follow.
