  Fix 21918 - Segfault for getParameterStorageClasses for invalid functions

  The type of a `FuncDeclaration` is set to `TypeError` if the `auto`
  inference fails. So `getParameters` has to check that the type is
  actually a `TypeFunction`.

  The additional check in `traits.d` prevents the invalid error message:
  ```
  Error: parameter index must be in range 0..0 not 0
  ```
