Don't early-propagate negative array lengths

There's no need for that and if the negative array length is not representable in 32 bit we'll end up producing a GT_CNS_INT node that has TYP_INT and a 64 bit value.

That's because the original type (always TYP_INT) of the GT_ARR_LENGTH is preserved when changing the node to GT_CNS_INT.
