Peter Maydell 4d9ad7f793 target-arm: Don't overflow when calculating value for signed VABAL
In the VABAL instruction we take the absolute difference of two
values of size x and store it in a result of size 2x. This means
we have to be careful to calculate the absolute difference using
a wide enough type that we don't accidentally overflow.
