* config/rs6000/rs6000.c (rs6000_return_in_memory): Test
TARGET_ALTIVEC_ABI.
(function_arg_boundary): Align 8 to 16 byte vectors like SPE.
Align 16 byte and larger vectors like Altivec.
(function_arg_advance): Pass any 16 byte vector like Altivec vector.
(function_arg): Same.
(rs6000_pass_by_references): Test TARGET_ALTIVEC_ABI.
