[AArch64][SVE] Asm: Support for vector element FP compare. Contains the following variants: - Compare with (elements from) other vector instructions: fcmeq, fcmgt, fcmge, fcmne, fcmuo. aliases: fcmle, fcmlt. e.g. fcmle p0.h, p0/z, z0.h, z1.h => fcmge p0.h, p0/z, z1.h, z0.h - Compare absolute values with (absolute values from) other vector. instructions: facge, facgt. aliases: facle, faclt. e.g. facle p0.h, p0/z, z0.h, z1.h => facge p0.h, p0/z, z1.h, z0.h - Compare vector elements with #0.0 instructions: fcmeq, fcmgt, fcmge, fcmle, fcmlt, fcmne. e.g. fcmle p0.h, p0/z, z0.h, #0.0 llvm-svn: 336182

[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
