re PR c++/60689 (Bogus error with atomic::exchange)

PR c++/60689
	* c-tree.h (c_build_function_call_vec): New prototype.
	* c-typeck.c (build_function_call_vec): Don't call
	resolve_overloaded_builtin here.
	(c_build_function_call_vec): New wrapper function around
	build_function_call_vec.  Call resolve_overloaded_builtin here.
	(convert_lvalue_to_rvalue, build_function_call, build_atomic_assign):
	Call c_build_function_call_vec instead of build_function_call_vec.
	* c-parser.c (c_parser_postfix_expression_after_primary): Likewise.
	* c-decl.c (finish_decl): Likewise.

	* c-common.c (add_atomic_size_parameter): When creating new
	params vector, push the size argument first.

	* c-c++-common/pr60689.c: New test.
