rs6000: Remove -maltivec={be,le}

This removes the -maltivec=be and -maltivec=le options.  Those were
deprecated in GCC 8.

Altivec will keep working on both BE and LE; it is just the BE-vectors-
on-LE that is removed (the other way around was never supported).

The main change is replacing VECTOR_ELT_ORDER_BIG by BYTES_BIG_ENDIAN
(and then simplifying).
