Disable register-register preloads for NaCl.
This disables, prefetches using the base reg + index reg
("[rb, ri]") style addressing mode.
We do not allow this addressing mode for other memory
instructions either and just to make sure we would also
like to sandbox this instruction which is only possible
for the base + immediate offset addressing mode.
