ec80e2693a Provide versions of the ARM eh_sjlj_setjmp instructions for non-VFP subtargets
such that the non-VFP versions have no implicit defs of VFP registers.
If any callee-saved VFP registers are marked as having been defined, the
prologue/epilogue code will try to save and restore them.
Radar 7770432.

e0c74fb1de ARM decoder emitter should print out useful information unconditionally when it
encounters decoding conflicts, instead of wrapping it inside the DEBUG() macro.

f8d0578e4c When emitting code for an add, don't force a SCEVUnknown wrapper around
a hoisted intermediate result if the intermediate result isn't an
Instruction.

4a2a683366 When looking for loop-invariant users, look through no-op instructions,
so that an unfortunately placed bitcast doesn't pin a value in a
register.

dc8446330f "On SPU, variables in the .bss section that are allocated with the .lcomm directive are not aligned on 16 byte boundaries. This causes misaligned loads, as the generated assembly assumes this "default" alignment.
this patch disables .lcomm in favour of '.local .comm'

Patch by Kalle Raisklia!
