[AArch64][SVE] Asm: Support for integer MUL instructions. This patch adds the following instructions: MUL - multiply vectors, e.g. mul z0.h, p0/m, z0.h, z1.h - multiply with immediate, e.g. mul z0.h, z0.h, #127 SMULH - signed multiply returning high half, e.g. smulh z0.h, p0/m, z0.h, z1.h UMULH - unsigned multiply returning high half, e.g. umulh z0.h, p0/m, z0.h, z1.h llvm-svn: 337358
