Break the arc-profile code out to a function like the notes emission code is,
and reorder the functions in the file.

The only functionality change is that we no longer modify the Module when the
Module has no debug info to use.

Add pass that expands pseudo instructions into target instructions after register allocation. Define pseudos that get expanded into mtc1 or mfc1 instructions.

Increase SubtargetFeatureKV Value and Implies fields to 64 bits since some targets are getting very close to 32 subtarget features. Also teach tablegen to error when there are more than 64 features to guard against undefined behavior. rdar://9282332

The transferValues() function can now handle both singly and multiply defined
values, as long as the resulting live range is known. Only rematerialized values
have their live range recomputed by extendRange().

The updateSSA() function can now insert PHI values in bulk across multiple
values in multiple target registers in one pass. The list of blocks received
from transferValues() is in layout order which seems to work well for the
iterative algorithm. Blocks from extendRange() are still in reverse BFS order,
but this function is used so rarely now that it doesn't matter.

Fix an infinite alternation in JumpThreading where two transforms would repeatedly undo each other.  The solution is to perform more aggressive constant folding to make one of the edges just folded away rather than trying to thread it.
