Add TargetInstrInfo::copyPhysReg hook and use it from LowerSubregs.
...
This target hook is intended to replace copyRegToReg entirely, but for now it
calls copyRegToReg.
Any remaining calls to copyRegToReg wil be replaced by COPY instructions.

Optimize some vfp comparisons to integer ones. This patch implements the simplest case when the following conditions are met:
...
1. The arguments are f32.
2. The arguments are loads and they have no uses other than the comparison.
3. The comparison code is EQ or NE.
e.g.
vldr.32 s0, [r1]
vldr.32 s1, [r0]
vcmpe.f32 s1, s0
vmrs apsr_nzcv, fpscr
beq LBB0_2
=>
ldr r1, [r1]
ldr r0, [r0]
cmp r0, r1
beq LBB0_2
More complicated cases will be implemented in subsequent patches.

Changes to ARM tail calls, mostly cosmetic.

Add explicit testcases for tail calls within the same module.
Duplicate some code to humor those who think .w doesn't apply on ARM.
Leave this disabled on Thumb1, and add some comments explaining why it's hard
and won't gain much.
