[WinEH] Remove unreachable blocks before preparation We remove unreachable blocks because it is pointless to consider them for coloring. However, we still had stale pointers to these blocks in some data structures after we removed them from the function. Instead, remove the unreachable blocks before attempting to do anything with the function. This fixes PR25099. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@249617 91177308-0d34-0410-b5e6-96231b3b80d8
