[AArch64][SVE] Asm: Integer divide instructions. This patch adds the following predicated instructions: UDIV Unsigned divide active elements UDIVR Unsigned divide active elements, reverse form. SDIV Signed divide active elements SDIVR Signed divide active elements, reverse form. e.g. udiv z0.s, p0/m, z0.s, z1.s (unsigned divide active elements in z0 by z1, store result in z0) sdivr z0.s, p0/m, z0.s, z1.s (signed divide active elements in z1 by z0, store result in z0) llvm-svn: 337369

[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
