(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.
