[llvm-commits] [LLVMdev] Spilled variables using unaligned moves

Actually it's split into two parts. One is just small hook at pre-RA  
level, which determines, whether stack realignment is really needed,  
and if yes - "reserves" it during RA.

The biggest part runs indeed at post-RA phase, but it just realigns  
stack and translates 'virtual offsets' into real ones. For aligned  
variables virtual offsets should be already aligned at this stage.
