Evan Cheng b659dff4eb Forgot about ARM::tPUSH. It also has a new writeback operand.

Evan Cheng e5801bd220 It's ok to spill a tGPR register as long as it's still allocated a low register.

David Greene 40c68ad3bb Re-apply 75490, 75806 and 76177 with fixes and tests. Efficiency comes
next.

Evan Cheng 57106d6dc0 Use TII->findCommutedOpIndices to find the commute operands (rather than guessing).

Evan Cheng 027d9f93ea Fix some sub-reg coalescing bugs where the coalescer wasn't updating the resulting interval's register class.

Evan Cheng 0794c6a083 Smarter isel of ldrsb / ldrsh. Only make use of these when [r,r] address is feasible.

Evan Cheng cd4cdd1157 Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically.
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.
