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.

This also pulls in a TargetMachine.h change from r176986 and changes
NaCl's intrinsics-bitmanip.ll test to account for register spills at O0.
FastISel was only enabled for iOS ARM and Thumb2, this patch enables it
for ARM (not Thumb2) on Linux and NaCl.
Thumb2 support needs a bit more work, mainly around register class
restrictions.
The patch punts to SelectionDAG when doing TLS relocation on non-Darwin
targets. I will fix this and other FastISel-to-SelectionDAG failures in
a separate patch.
The patch also forces FastISel to retain frame pointers: iOS always
keeps them for backtracking (so emitted code won't change because of
this), but Linux was getting much worse code that was incorrect when
using big frames (such as test-suite's lencod). I'll also fix this in a
later patch, it will probably require a peephole so that FastISel
doesn't rematerialize frame pointers back-to-back.
The test changes are straightforward, similar to:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130513/174279.html
They also add a vararg test that got dropped in that change.
I ran all of test-suite on A15 hardware with --optimize-option=-O0 and
all the tests pass.

test cases require fixes to fast-isel before the verifier can be enabled.

SimplifyAddress to handle either a 12-bit unsigned offset or the ARM +/-imm8
offsets (addressing mode 3). This enables a load followed by an integer
extend to be folded into a single load.
For example:
ldrb r1, [r0] ldrb r1, [r0]
uxtb r2, r1 =>
mov r3, r2 mov r3, r1
