  Log Message:
  -----------
  [Clang] Check for abstract parameters only when functions are defined.

The C++ standard allows abstract parameters in deleted functions
and in function declarations

> The type of a parameter or the return type for a function definition
> shall not be a (possibly cv-qualified) class type that is
> incomplete or abstract within the function body
> unless the function is deleted.
