Typically you *can't* change the signature of a builtin because the builtin is itself a language feature that's documented to have a particular signature.  If you've made a builtin purely for use in generated AST, that's pretty unfortunate, and you should consider whether you actually have to do that instead of e.g. synthesizing a call to an allocation function the same way that we do in `new` expressions.

Well, the intention was not *only* use it in AST, it could be used by clients to ask LLVM to handle overaligned frame. I'm not sure how many use cases that could have, so in the updated patch, I've removed it.
