tm.texi (TARGET_MD_ASM_CLOBBERS): Adjust wording to not imply that this is called once, independent of asms in code.

	* doc/tm.texi (TARGET_MD_ASM_CLOBBERS): Adjust wording to not
	imply that this is called once, independent of asms in code.
	Adjust to now being pased output and input lists.  Mention helper
	function decl_overlaps_hard_reg_set_p.
	* hooks.c (hook_tree_tree_tree_tree_3rd_identity): Rename from
	hook_tree_tree_identity and to take three trees, returning third.
	* hooks.h (hook_tree_tree_tree_tree_3rd_identity): Adjust the
	prototype.
	* stmt.c: include hard-reg-set.h before tree.h.
	(decl_overlaps_hard_reg_set_p): New function, broken out from...
	(decl_conflicts_with_clobbers_p): Call
	decl_overlaps_hard_reg_set_p.
	(expand_asm_operands): Pass output and input lists in call to
	targetm.md_asm_clobbers.
	* target-def.h (TARGET_MD_ASM_CLOBBERS): Define as
	hook_tree_tree_tree_tree_3rd_identity.
	* target.h (struct gcc_target.md_asm_clobbers): Take three tree
	parameters.
	* tree.h [HARD_CONST] (decl_overlaps_hard_reg_set_p): Prototype.
	* config/i386/i386.c (ix86_md_asm_clobbers): Adjust to three
	parameters, first two unused.
	* config/cris/cris.c (cris_md_asm_clobbers): Adjust to added
	parameters.  Only add MOF to clobbers if there's no 'h' mentioned
	in constraint letters and MOF is not mentioned as a asm-declared
	register in neither of the input and output lists.
