Log Message:
-----------
- Add the earlyclobber flag to instructions that cannot have the same register in the source and destination operands like postinc/predec memory instrs. This change exposed a bug in llvm's spiller, so include a workaround until it gets fixed.
- Implement register masks for call instructions.
- Add more asserts to the instruction pseudo expander.
- Implement 8bit push/pop for saving/restoring callee-saved registers. This means that there's no need anymore to save a whole register pair when only one part is used.
