* tree-inline.c (copy_tree_r): Don't duplicate constants, they're

	shared anyway.

	PR pch/13361
	* c-typeck.c (constructor_asmspec): Delete.
	(struct initializer_stack): Delete field 'asmspec'.
	(start_init): Delete saving of asmspec.
	(finish_init): Don't update constructor_asmspec.
	* dwarf2out.c (rtl_for_decl_location): Duplicate string from tree.
	* stmt.c (expand_asm): Duplicate strings from tree.
	(expand_asm_operands): Likewise.
	* tree.c (tree_size): Update computation of size of STRING_CST.
	(make_node): Don't make STRING_CST nodes.
	(build_string): Allocate string with tree node.
	(tree_code_size): Clean up assertions, don't allow requests
	for "the size of a STRING_CST".
	* tree.def (STRING_CST): Update comment.
	* tree.h (TREE_STRING_POINTER): Adjust for change to STRING_CST.
	(tree_string): Place contents of string in tree node.
	* config/sh/sh.c (sh_handle_sp_switch_attribute): Duplicate string
	from tree.
