Fix horrible non-termination bug in LiveVariables. The issue was that
the liveness state of block-level expressions could oscillate because
of two issues:
- The initial value before a merge was not always set to "Top"
- The set of live block-level expressions is a union, not an intersection
This fixes <rdar://problem/650084>.
