[PATCH] D20155: [ARM] PR25722 Support and tests for transform of LDR rt, = to MOV

[Peter Smith via llvm-commits]

I've updated the patch to not do any kind of translation when the destination is SP or PC. Now that I think about it I have seen bootcode where the stack pointer has been set using ldr sp,=value so this would have caused problems.

I've added changed the ARM check from hasV8MBaseline to has v6T2Ops as that matches TableGen and befits the ARM presence of MOVW in V6T2 onwards.
