-Subject: [rust-lang/llvm#54] [SimplifyCFG] Correctly test for unconditional
- branches in GetCaseResults
-
-GetCaseResults assumed that a terminator with one successor was an
-unconditional branch.  This is not necessarily the case, it could be a
-cleanupret.
-
-Strengthen the check by querying whether or not the terminator is
-exceptional.
