I committed the attached patch to fixes the problems discovered so far.

This patch adds the TARGET_SINGLE_FLOAT and TARGET_DOUBLE_FLOAT
conditionals in function_arg and function_arg_advance with the correct grouping.

It also reverts the conditionals that added tests for mode where there was
none before, breaking support for other FP modes.

        * config/rs6000/rs6000.c (USE_FP_FOR_ARG_P): Revert
        TARGET_DOUBLE_FLOAT, TARGET_SINGLE_FLOAT.
        (function_arg_advance): Condition on TARGET_DOUBLE_FLOAT,
        TARGET_SINGLE_FLOAT.
        Revert SCALAR_FLOAT_MODE_P condition.
        (function_arg): Condition on TARGET_DOUBLE_FLOAT,
        TARGET_SINGLE_FLOAT.
        (rs6000_function_value): Revert TARGET_DOUBLE_FLOAT,
        TARGET_SINGLE_FLOAT.
