Avoid many "variable 'Sub' set but not used [-Wunused-but-set-variable]" warnings
with gcc-4.6.  The warning is wrong, since Sub *is* used (perhaps gcc is confused
because the use of Sub is constant folded away?), but since it is trivial to avoid,
and massively reduces the amount of warning spew, just workaround the wrong warning.

Keep track of the call instructions whose clobber lists were skipped during fast
register allocation.

Process all of the clobber lists at the end of the function, marking the
registers as used in MachineRegisterInfo.

This is necessary in case the calls clobber callee-saved registers (sic).

Fixed a bug during widening where we would avoid legalizing a node.  When we
replace an OpA with a widened OpB, it is possible to get new uses of OpA due to CSE
when recursively updating nodes.  Since OpA has been processed, the new uses are
not examined again.  The patch checks if this occurred and it it did, updates the
new uses of OpA to use OpB.
