Simplified GIMPLE IL builder functions.

	* gimple.c (create_gimple_tmp): New.
	(get_expr_type): New.
	(build_assign): New.
	(build_type_cast): New.
	* gimple.h (enum ssa_mode): Define.
	(gimple_seq_set_location): New.
	* asan.c (build_check_stmt): Change some gimple_build_* calls
        to use build_assign and build_type_cast.
