Be more clever about calculating live variables through new basic blocks.
...
When splitting a critical edge, the registers live through the edge are:
- Used in a PHI instruction, or
- Live out from the predecessor, and
- Live in to the successor.
This allows the coalescer to eliminate even more phi joins.

The verify() call of CPEIsInRange() isn't right for the assertion check of

constant pool ranges, as CPEIsInRange() makes conservative assumptions about
the potential alignment changes from branch adjustments. The verification,

effects on alignment are known and already taken into account. The sanity
check in verify should check the range directly instead.
