ROOT CAUSE: This is an interaction between IFTI and property syntax.

PATCH: At the end of CastExp::semantic, make sure that the function has a type.

=====
Some similar cases cause the compiler to do strange things (see below), so I'm
not completely satisfied with the patch. But let's just fix the segfault.

struct Bug3775 {
  static int byLine()()    { return 1;   }
}
void main(){ auto xxx = Bug3775.byLine; } // accepted; xxx is an int.
void main(){ int xxx = Bug3775.byLine; } // rejected: (Bug3775).byLine() has no
value
