Nick Lewycky d5061a9268 Fix logical error when detecting lifetime intrinsics. ... Don't replace a gep/bitcast with 'undef' because that will form a "free(undef)" which in turn means "unreachable". What we wanted was a no-op. Instead, analyze the whole tree and look for all the instructions we need to delete first, then delete them second, not relying on the use_list to stay consistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136752 91177308-0d34-0410-b5e6-96231b3b80d8		2011-08-03 00:43:35 +00:00
