[PATCH v3 13/15] target/arm: Use expand_pred_b in mve_helper.c |

Use the function instead of the array directly.
Because the function performs its own masking, via the uint8_t
parameter, we need to nothing extra within the users: the bits
above the first 2 (_uh) or 4 (_uw) will be discarded by assignment
to the local bmask variables, and of course _uq uses the entire
uint64_t result.
