Between scheduling regions, correctly maintain anti-dep breaking state so that we don't incorrectly rename registers that span these regions.

First bitcase use may not lead to a dbg.declare intrinsic. Iterate uses until one find's dbg.declare intrinsic.

bunch of associated comments, because it doesn't have anything to do
with DAGs or scheduling. This is another step in decoupling MachineInstr
emitting from scheduling.

on it until someone feels compelled to implement this.

heuristic to place it nearest the stack pointer in that case, rather than
nearest the frame pointer.

the second (store) instruction in SpillSlotToUsesMap
consistently.  I don't think this matters functionally,
but it's cleaner and Evan wants it this way.

to spill after all, we weren't handling 2-instruction
spill sequences correctly (PPC Altivec).  We need to
remove the store in this case.  Removing the other
instruction(s) would be goodness but is not needed for
correctness, and isn't done here.  7331562.

Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic.
Update users of getMallocArraySize() to not bother calling isArrayMalloc() as well.
