indirect branches correctly. Under some circumstances, this led to the deletion of basic blocks that were the destination of indirect branches. In that case it left indirect branches to nowhere in the code. This patch replaces, and is more general than either of the previous fixes for indirect-branch-analysis issues, r181161 and r186461. For other branches (not indirect) this refactor should have *almost* identical behavior to the previous version. There are some corner cases where this refactor is able to analyze blocks that the previous version could not (e.g. this necessitated the update to thumb2-ifcvt2.ll). <rdar://problem/14464830> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186735 91177308-0d34-0410-b5e6-96231b3b80d8
