0c525ca72f Special cases are needed in renumbering when dealing with renumbering after a PHI has been removed. The interval previously defined
by the PHI needs to be extended to the beginning of its basic block, and the intervals that were inputs need to be trimmed to the end 
of their basic blocks.

020decc2b4 In order to avoid reprocessing a register more than once, we need to add it
to the handled set so it will get filtered out in future iterations.

d7dcbecdbc Make the remapping of interval indices (particularly ending indices) more robust.
This is tricky business, and will probably take a few more iterations to get
the last kinks out of it.

fc74abfba5 Enable first-class aggregates support.
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.
