44047da675 ARM Darwin default relocation model is PIC.
This matches clang, so default options in llc and friends are now closer to
clang's defaults.

93f2ebb5e7 Simplify printing of ARM shifted immediates.
Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
 displayed.

eae10d6163 Add ARM fast-isel support for materializing the address of a global in cases where the global uses an indirect symbol.

93ffb875ad Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent.
The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).

919bf1ca71 Make FastEmit_ri_ try a bit harder to succeed for supported operations; FastEmit_i can fail for non-Thumb2 ARM. Makes ARMSimplifyAddress work correctly, and reduces the number of fast-isel bailouts on non-Thumb ARM.

1940912660 Switch to ImmLeaf (which can be used by FastISel) for a few more common ARM/Thumb2 patterns.

ba0cef1b0b Add trunc->branch support, this won't help with clang's i8->i1 truncations
for bools, but is a start.

22b01f0d76 Recommit this change and remove the failing part of the test - it didn't
pass in the first place and was masked by earlier failures not warning
and aborting the block.

ba758d0df4 This should be still failing, but is. Disable it with the
forget-me-stick for now.

9c34a7831d Re-apply r113679, which was reverted in r113720, which added a paid of new instcombine transforms
to expose greater opportunities for store narrowing in codegen.  This patch fixes a potential
infinite loop in instcombine caused by one of the introduced transforms being overly aggressive.

d4aaabfa74 Revert 113679, it was causing an infinite loop in a testcase that I've sent
on to Owen.
