8338ff5ff1 Fix a bug that was causing the elimination phase not to replace values when it should be.
With this patch, GVN-PRE now correctly optimizes the example from the thesis.

Many thanks to Daniel Berlin for helping me find errors in this.

2513330de8 Factor live variable analysis so it does not do register coalescing
simultaneously.  Move that pass to SimpleRegisterCoalescing.

This makes it easier to implement alternative register allocation and
coalescing strategies while maintaining reuse of the existing live
interval analysis.
