Description
When enabled on x86 platforms, OptoScheduling often crashes.  This bug is intended to encompass all C2 scheduling problems resulting in VM failure.

Additional scheduling cleanups may also be addressed.

EVALUATION

The are roughly four parts to this fix: elimination of crashes, deletion of dead code, 
refactoring of parameters, and (possibly) fixing of any missed dependecncies.
