I found some problems ....
TARGET_POINTER_MODE and TARGET_ADDR_SPACE_POINTER mode only return one
mode, but now we have multiple valid modes: DImode, V2DImode, V4DImode,
etc. They also return scalar_int_mode so I can't even invent a new
address space for the vector pointers.
Same for TARGET_ADDR_SPACE_ADDRESS_MODE.
TARGET_VALID_POINTER_MODE and TARGET_ADDR_SPACE_VALID_POINTER_MODE only
accept scalar_int_mode, so automatically exclude vector pointers.
These can be patched to use plain machine_mode, perhaps, or keep them
all scalar and add a new TARGET_ADDR_SPACE_ALLOWS_VECTOR_POINTERS to fix
the problem at the call sites, which might make more sense?
