Add another test case to show the precision of RegionStore over

BasicStore. In this example, BasicStore would lose information about
the pointer in path after '*path++', causing the analyzer to falsely
flag a null dereference. This addresses <rdar://problem/7191542>.

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.
