[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

[AArch64][SVE] Asm: Enable instructions to be prefixed. This patch enables instructions that are destructive on their destination- and first source operand, to be prefixed with a MOVPRFX instruction. This patch also adds a variety of tests: - positive tests for all instructions and forms that accept a movprfx for either or both predicated and unpredicated forms. - negative tests for all instructions and forms that do not accept an unpredicated or predicated movprfx. - negative tests for the diagnostics that get emitted when a MOVPRFX instruction is used incorrectly. This is patch [2/2] in a series to add MOVPRFX instructions: - Patch [1/2]: https://reviews.llvm.org/D49592 - Patch [2/2]: https://reviews.llvm.org/D49593 Reviewers: rengolin, SjoerdMeijer, samparker, fhahn, javed.absar Reviewed By: SjoerdMeijer Differential Revision: https://reviews.llvm.org/D49593 llvm-svn: 338261
