Return an expression valid as a return value for the two macros
FUNCTION_ARG and FUNCTION_VALUE.
- SIZE is the size in bytes of the vector.
- BASE_MODE is the argument's base machine mode.
+ SIZE is the size in bytes of the vector (at least 8 bytes).
REGNO is the FP hard register the vector will be passed in. */
