Evan Cheng 4e7ff941f1 Frame index can be negative.

Evan Cheng a41d3bcb12 MRegisterInfo::getLocation() is a really bad idea. Its function is to calculate the offset from frame pointer to a stack slot and then storing the delta in a MachineLocation object. The name is bad (it implies a getter), and MRegisterInfo doesn't need to know about MachineLocation. 
Replace getLocation() with getFrameIndexOffset() which returns the delta from frame pointer to stack slot. Dwarf writer can then use the information for whatever it wants.

Evan Cheng 8e136a9dc4 - Move getPhysicalRegisterRegClass() from ScheduleDAG to MRegisterInfo. 
- Added ability to emit cross class register copies to the BBRU scheduler.
- More aggressive backtracking.

Jim Laskey f6c63fec92 Repair debug frames as a prelude to eh_frames. Switched to using MachineMoves 
by value so that clean up is less confusing (these vectors tend to be small.)
