decl.c (pop_cp_function_context): Don't call free on a NULL pointer.

Browse Source 
* decl.c (pop_cp_function_context): Don't call free on a NULL
	pointer.
	* semantics.c: Include ggc.h.
	(expand_body): Do garbage-collection after processing a template
	function.  Clear DECL_SAVED_TREE after generating RTL for a
	function.
	* Makefile.in (semantics.o): Depend on ggc.h.
