Out Of SSA Cleanup
Stage one of RABLET. Out of SSA requires some modifications in order to proceed. There is a lot of code and abstractions in this code which are no longer required, and some algorithmic improvements. I also need the ability to keep a funciton in SSA limbo for a period of time in order to proceed with the register pressure reduction and integration with RTL generation plans. More info on RABLET is at http://gcc.gnu.org/ml/gcc/2006-06/msg00736.html
- These changes should be ready by 2006-10-31.
- Out of SSA will run faster and use less memory.
- This first phase requires changing some of the algorithms and data structure used in out of ssa.
