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>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63421 91177308-0d34-0410-b5e6-96231b3b80d8
