	* tree-sra.c (build_access_from_expr_1): The first parameter type
	changed to simple tree.
	(build_access_from_expr): Likewise, gsi parameter was eliminated.
	(scan_assign_result): Renamed to assignment_mod_result, enum elements
	renamed as well.
	(build_accesses_from_assign): Removed all parameters except for a
	simple gimple statement.  Now returns a simple bool.

	sra_modify_function_body and ipa_sra_modify_function_body.  Removed all
	parameters and updated both callers.
	(sra_modify_expr): Removed parameter data.
	(sra_modify_function_body): New function.
	(perform_intra_sra): Call sra_modify_function_body to modify the
	function body.
	(replace_removed_params_ssa_names): Parameter data changed into
	adjustments vector.

	changed the parameter dont_convert to convert with the opposite
	meaning.
	(sra_ipa_modify_assign): Parameter data changed into adjustments
	vector, return value changed to bool.
	(ipa_sra_modify_function_body): New function.
