Subject: Turns out AnalyzeBranch can modify the mbb being analyzed. This is a
 nasty suprise to some callers, e.g. register coalescer. For now, add an
 parameter that tells AnalyzeBranch whether it's safe to modify the mbb. A
 better solution is out there, but I don't have time to deal with it right
 now.
