Issue an error for improper use of record_info/2 in a fun
`record_info/2` is a pseudo-function that requires literal arguments
known at compile time. Therefore, the following usage is illegal:
f() -> fun record_info/2.
However, `erl_lint` did not issue a compilation error for this usage,
and the compiler would crash in a later pass.
