Fix PR8445: a block with no predecessors may be the entry block, in which case it isn't unreachable and should not be zapped. The check for the entry block was missing in one case: a block containing a unwind instruction. While there, do some small cleanups: "M" is not a great name for a Function* (it would be more appropriate for a Module*), change it to "Fn"; use Fn in more places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117224 91177308-0d34-0410-b5e6-96231b3b80d8 2010-10-24 12:23:30 +00:00			`; RUN: opt %s -simplifycfg -disable-output`
