[PATCH, rs6000] Fix PR92760 by checking VECTOR_MEM_NONE_P instead

Hi, PR92760 exposed one issue that VECTOR_UNIT_NONE_P (V2DImode) is true on Power7 then we won't return it as preferred_simd_mode but ISA 2.06 (Power7) does introduce partial support on vector doubleword (very limitted) and more basic support origins from ISA 2.07 (Power8) though. To make vector
