Add AccessSemantics support for calling typenames.

Add AccessSemantics support for calling typenames.

This adds AccessSemantics support for constructions like:

  class C {}
  main() {
    C();
  }

Even though this will always lead to a runtime error, it only produces
a warning at compile time.  Therefore AccessSemantics needs to
classify it correctly in order to allow the compilation back-end to
produce the correct runtime error.

Apologies for the extra code motion--the last time I edited this file was before
I'd gotten in the habit of sorting declarations.
