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

instruction (terminator?) following the allocation so I
am allowing the same assumption.

My last coalescer fix introduced a subtler one. It's aborting a commuting optimization too late and left the live intervals to be out of sync with instructions. This fixes 8b10b.

alignment of the generated constant pool entry to the
desired alignment of a type.  If we don't do this, we end up
trying to do movsd from 4-byte alignment memory.  This fixes
450.soplex and 456.hmmer.

1. Use the same value# to represent unknown values being merged into sub-registers.
2. When coalescer commute an instruction and the destination is a physical register, update its sub-registers by merging in the extended ranges.

scheduled in multiple regions, liveness data used by the
anti-dependence breaker is carried from one region to the next, however
the information reflects the state of the instructions before scheduling.
After scheduling, there may be new live range overlaps. Handle this by
pessimizing the liveness data carried between regions to the point where
it will be conservatively correct now matter how the earlier region is
scheduled. This fixes a miscompilation in 176.gcc with the post-RA
scheduler enabled.

Introduce helpers to access debug info for global variables. Also introduce a

If a function is marked alwaysinline, it must be inlined (possibly for correctness). Do so even if the callee has dynamic alloca and the caller doesn't.
