a581d6d202 Tidy up PMStack. Add a bunch of consts, use std::vector instead of 
std::deque, since this is a stack and only supports push/pop on
one end, and remove an unimplemented declaration.

6944ea9801 Lazily defer duplicating the live interval we are splitting until we know it is 
necessary.

Sometimes, live range splitting doesn't shrink the current interval, but simply
changes some instructions to use a new interval. That makes the original more
suitable for spilling. In this case, we don't need to duplicate the original.

a37c7509bf Add LiveInterval::RenumberValues - Garbage collection for VNInfos. 
After heavy editing of a live interval, it is much easier to simply renumber the
live values instead of trying to keep track of the unused ones.

26726984fe Don't try to verify LiveIntervals for physical registers. 
When a physical register is in use, some alias of that register has a live
interval with a relevant live range. That is the sad state of intervals after
physreg coalescing of subregs, and it is good enough for correct register
allocation.

6d53fded19 Fix eabi calling convention when a 64 bit value shadows r3. 
Without this what was happening was:

* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

0cd2ae5158 Add the Optimize Compares pass (disabled by default). 
This pass tries to remove comparison instructions when possible. For instance,
if you have this code:

   sub r1, 1
   cmp r1, 0
   bz  L1

and "sub" either sets the same flag as the "cmp" instruction or could be
converted to set the same flag, then we can eliminate the "cmp" instruction all
together. This is a important for ARM where the ALU instructions could set the
CPSR flag, but need a special suffix ('s') to do so.
