[committed][AArch64] Predicated SVE comparison folds

This patch adds SVE patterns that combine a PTRUE-predicated comparison with a separate AND. The main benefit is for optimising ANDs with the loop predicate, as in the testcase. However, one of the potential drawbacks is that it triggers even for cases in which two naturally-parallel comparisons
