[PowerPC] Eliminate integer compare instructions - vol. 1 This patch is the first in a series of patches to provide code gen for doing compares in GPRs when the compare result is required in a GPR. It adds the infrastructure to select GPR sequences for i1->i32 and i1->i64 extensions. This first patch handles equality comparison on i32 operands with the result sign or zero extended.

[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.

[PowerPC] Eliminate integer compare instructions - vol. 1 This patch is the first in a series of patches to provide code gen for doing compares in GPRs when the compare result is required in a GPR. It adds the infrastructure to select GPR sequences for i1->i32 and i1->i64 extensions. This first patch handles equality comparison on i32 operands with the result sign or zero extended.
