Spiller may unfold load / mod / store instructions as an optimization when the would be loaded value is available in a register. It needs to check if it's legal to clobber the register. Also, the register can contain values of multiple spill slots, make sure to check all instead of just the one being unfolded.

Add newlines at end of file (this can annoy gcov)

Reorganization: Move the Spiller out of VirtRegMap.cpp into its own files. No (intended) functionality change.
