Sometimes there is only one 'resume' instruction per function. In those situations, we don't need a separate block for the call to _Unwind_Resume. In fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0. If we have a single 'resume' instruction, just generate the call within that block. <rdar://problem/10694814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149159 91177308-0d34-0410-b5e6-96231b3b80d8
