[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][NFC] Avoid checking non-relevant .cfi instructions Summary: This is brought up in https://reviews.llvm.org/D64662?id=209923#inline-599490 CFI information are non-relevant to quite some testcases, we should get rid of checking them when its unecessary. This patch avoid generating cfi info in testcases that are not testing prolog/epilog or exception handling.
