[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
