Jim Grosbach b98ab91e39 Thumb1 register to register MOV instruction is predicable. 
Fix a FIXME and allow predication (in Thumb2) for the T1 register to
register MOV instructions. This allows some better codegen with
if-conversion (as seen in the test updates), plus it lays the groundwork
for pseudo-izing the tMOVCC instructions.

Cameron Zwarich 2e252de512 Fix an issue where the two-address conversion pass incorrectly rewrites untied 
operands to an early clobber register. This fixes <rdar://problem/9566076>.
