This moves the willReturn() helper from CallBase to Instruction, so that it can be used in a more generic manner. This will make it easier to fix additional passes (ADCE and BDCE), and will give us one place to change if additional instructions should become non-willreturn (e.g. there has been talk about handling volatile operations this way).

      

I have also included the IntrinsicInst workaround directly in here, so that it gets applied consistently. (As such this change is not entirely NFC -- FuncAttrs will now use this as well.)
