[AArch64][SVE] Asm: Predicated integer reductions. This patch adds support for various integer reduction operations: SADDV signed add reduction to scalar UADDV unsigned add reduction to scalar SMAXV signed maximum reduction to scalar SMINV signed minimum reduction to scalar UMAXV unsigned maximum reduction to scalar UMINV unsigned minimum reduction to scalar ANDV logical AND reduction to scalar ORV logical OR reduction to scalar EORV logical EOR reduction to scalar The reduction is predicated, e.g. smaxv s0, p0, z1.s performs a signed maximum reduction on active elements in z1, and stores the (signed max value) result in s0. llvm-svn: 338126
