[AArch64][SVE] Asm: Support for unpredicated FP operations. This patch adds support for the following unpredicated floating-point instructions: FADD Floating point add FSUB Floating point subtract FMUL Floating point multiplication FTSMUL Floating point trigonometric starting value FRECPS Floating point reciprocal step FRSQRTS Floating point reciprocal square root step The instructions have the following assembly format: fadd z0.h, z1.h, z2.h and have variants for 16, 32 and 64-bit FP elements. llvm-svn: 337383

[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
