not assigned to a named value.

demonstrating instructions, we will follow an instruction with a comment

- The calling conventions of the caller and callee must match.
- All ABI-impacting function attributes, such as sret, byval, inreg,
returned, and inalloca, must match.
+ - The callee must be varargs iff the caller is varargs. Bitcasting a
+ non-varargs function to the appropriate varargs type is legal so
+ long as the non-varargs prefixes obey the other rules.
Tail call optimization for calls marked ``tail`` is guaranteed to occur if
the following conditions are met:
