[AArch64] Add SVE conditional integer unary patterns
This patch adds patterns to match conditional unary operations
on integers. At the moment we rely on combine to merge separate
arithmetic and vcond_mask operations, and since the latter doesn't
accept zero operands, we miss out on the opportunity to use the
movprfx /z alternative. (This alternative is tested by the ACLE
patches though.)
