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
be constant to be moved out of loops."

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.'

Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.
