Debugger for Register Allocation

Hi, Evan,

This looks quite useful. Do you think you can incorporate the code
output the debugging info in smira to tot?

No problem. Actually, the spiller code is very small. If you have time, take a look:

To use it correctly, spill fusion must be disabled, otherwise the debugger will report the omitted load/stores as errors.
