We're using V64DImode to represent a vector of 64 64-bit pointers. The 
architecture can hold this in a pair of V64SImode registers; it is not 
equivalent to 128 consecutive smaller registers, like NEON does.

We could use plain DImode to get the same effect from print_operand, but 
that then chooses the wrong alternative, or whole wrong insn pattern and 
bad things would happen.

Or, do you mean something else?
