Right, please don't do that. :)

I would suggest to model the interface after gcc_jit_context_new_call
(but still keep it separate because even though attributes with
arguments are syntactically pretty much like function calls in the C
front end, semantically, they are not).
I'm not sure where the argument list checking for attributes happens
(at least it's not part of the C parser). It would be preferable if
there were at least some consistency checks when using the JIT
interface, instead of silently generating broken code.
