change with alloca calls.

 * With the 32-bit ABI, the save location is just below the general
register save area, and is accessed via the frame pointer like the rest
of the save areas.  This is an optional slot, so it must only be created
if any of CR2, CR3, and CR4 were modified.

 * For both ABIs, save/restore logic is generated only if one of the
nonvolatile CR fields were modified.

I also took this opportunity to clean up an extra FIXME in
PPCFrameLowering.h.  Save area offsets for 32-bit GPRs are meaningless
for the 64-bit ABI, so I removed them for correctness and efficiency.

Fixes PR13708 and partially also PR13623. It lets us enable exception handling
on PPC64.

sub-register indexes in an irregular way, the masks may conservatively
report that two sub-register indices overlap when the eventually

Reorganize MachineScheduler interfaces and publish them in the header.

The Hexagon target decided to use a lot of functionality from the
target-independent scheduler. That's fine, and other targets should be
able to do the same. This reorg and API update makes that easy.

For the record, ScheduleDAGMI was not meant to be subclassed. Instead,
new scheduling algorithms should be able to implement
MachineSchedStrategy and be done. But if need be, it's nice to be

scheduler is somewhat more apt to break that way though.

Don't attempt to use flags from predicated instructions.

The ARM backend can eliminate cmp instructions by reusing flags from a
nearby sub instruction with similar arguments.

Don't do that if the sub is predicated - the flags are not written
