* optabs.h (force_expand_binop): Declare.

	* optabs.c (force_expand_binop): Export.
	* stmt.c (shift_return_value): Delete.
	(expand_return): Don't call it.
	* expr.h (shift_return_value): Declare.
	* calls.c (shift_returned_value): Delete in favor of...
	(shift_return_value): ...this new function.  Leave the caller to check
	for non-BLKmode values passed in the msb of a register.  Take said mode
	and a shift direction as argument.  Operate on the hard function value,
	not a pseudo.
	(expand_call): Adjust accordingly.
	* function.c (expand_function_start): If a non-BLKmode return value
	is padded at the last significant end of the return register, use the
	return value's natural mode for the DECL_RESULT, not the mode of the
	padded register.
	(expand_function_end): Shift the same sort of return values left by
	the appropriate amount.
