334143d304 I give up on trying to use reader/writer locks for recursive type refinement. Use a recursive mutex instead, which will (in theory) generate more contention, but is really
a much more natural fit for what's going on during recursive type refinement.

459a7c6b6a Remove special handling of implicit_def. Fix a couple more bugs in liveintervalanalysis and coalescer handling of implicit_def.
Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def.

20c568f366 Add an "alignment" field to the MachineFunction object. It makes more sense to

alignment is decided upon.

like.

4784f1fc73 Add a bit IsUndef to MachineOperand. This indicates the def / use register operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them.
The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.

This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.
