Log Message:
lint: add type details to message about 'sizeof(function)'
The code in add_function is severely broken, it mixes up the return type
of the function with the argument types. For now, at least show the
guessed type in the diagnostic, to allow human readers quickly spot the
bug.
Extend the test cases in decl_direct_abstract.c to show that the
behavior differs unreasonably if the first parameter of the function is
equal to its return type.
