This patch folds signed SVE division where all divisor elements are any power of 2 to svasr. Tests were added to check 1) whether the transform is applied and 2) to check correctness for a variety of values.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
