multiple-valued return values, so that the name CreateRet is just for
creating plain ret statements.

This is tricky business, and will probably take a few more iterations to get
the last kinks out of it.

mmx needs its own fancy shuffle logic based on unpack; for now we get correct but awful code.

and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow
constants to be rematerialized in PIC mode -- the extra indirection is a
complication.

regressions because CodeGen is currently not able to remat such loads.

large numbers of CBE regressions caused by r53958.

Store the predecessor MBB in the PHIUnion, rather than an index, since the indices will change after renumbering.

Fix a catastrophic PPC64 ABI bug: i32 operands which are passed in memory (all of the parameter registers are used) are loaded from sp offsets that were off by 4.

This allows instructions like loads from global variables declared to

they appear in words. This would cause things like the "128" in "VR128"
to be highlighted. This patch fixes the highlighting by only recognizing 
constants when they have word breaks around them.'
