Specifically:
r186489 - Fix ARMFastISel::ARMEmitIntExt shift emission
r183794 - ARM FastISel fix sext/zext fold
r183601 - Fix unused variable warning from my previous patch
r183551 - ARM FastISel integer sext/zext improvements
These should fix some failures that I had run into back then, as well as make ARM FastISel faster because it doesn't go to SelectionDAG.

Revert this until we fix i1 sext. Currently, it uses LSL and ASR,
which are pseudo-instructions and get dropped on the floor when
generating .o files. We'll fix that, but for now revert to green
the bots.

Rename countTrailingZeros to the older CountTrailingZeros_32, mark as localmod.
These patches fix correctness issues with ARM FastISel, and should make it faster while generating better code.
