631ee4b89f Use the EdgeBundles analysis in X86FloatingPoint instead of recomputing CFG
bundles in the pass.

8dd070edc2 Turn the EdgeBundles class into a stand-alone machine CFG analysis pass.
The analysis will be needed by both the greedy register allocator and the
X86FloatingPoint pass. It only needs to be computed once when the CFG doesn't
change.

This pass is very fast, usually showing up as 0.0% wall time.
