[RFA]: Clean up C++ type handling in linespec parsing

[Jim Blandy <jimb at zwingli dot cygnus dot com>]

2001-03-15  Jim Blandy  <jimb@redhat.com>

	* linespec.c (find_methods): Just call CHECK_TYPEDEF on t, rather
	than asking for sym_class's type; that's circuitous.  Remove
	sym_class, since the last use of it is gone.  (This is a minor
        revision of a change from Dan Berlin.)
