Subject: ada: Fix internal error on protected type with -gnatc -gnatR

ada: Fix internal error on protected type with -gnatc -gnatR

It occurs when the body of a protected subprogram is processed, because the
references to the components of the type have not been properly expanded.

gcc/ada/

	* gcc-interface/trans.cc (Subprogram_Body_to_gnu): Also return early
	for a protected subprogram in -gnatc mode.
