[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.

 ; The purpose of the test case is to ensure that a spill that happens during
 ; intermediate calculations for a comparison performed in a GPR spills the
 ; full register. Some i32 comparisons performed in GPRs use code that uses
 ; the full 64-bits of the register in intermediate stages. Spilling such a value
 ; as a 32-bit value is incorrect.
