5c9283696b SPU section handling is really huge mess. Replace remaining TAI calls for sections with explicit names in order not to block existing backends during section handling migration. SPU folks! Please consider using new section handling facility someday.

456b33b615 Refactor the constant folding code into it's own function. And call it from both 
the SelectionDAG and DAGCombiner code. The only functionality change is that now
the DAG combiner is performing the constant folding for these operations instead
of being a no-op.

This is *not* in response to a bug, so there isn't a testcase.

bc29bec7f8 Next round of earlyclobber handling. Approach the 
RA problem by expanding the live interval of an
earlyclobber def back one slot.  Remove
overlap-earlyclobber throughout.  Remove 
earlyclobber bits and their handling from
live internals.
