TYPE_SYMTAB_POINTER was only used by sdbout.c, so can now be removed.

gcc/
	* tree-core.h (tree_type_common): Delete pointer field of
	tree_type_symtab.
	* tree.c (copy_node): Clear TYPE_SYMTAB_DIE instead of
	TYPE_SYMTAB_POINTER.
	* tree.h (TYPE_SYMTAB_POINTER): Delete.
	(TYPE_SYMTAB_IS_POINTER): Delete.
	(TYPE_SYMTAB_IS_DIE): Renumber.
