[LLVM][AArch64][Assembly]: Add FAMINMAX assembly/disasse… (llvm#70115)
…mbly. This patch adds the feature flag FAMINMAX and the assembly/disassembly for the following instructions of NEON, SVE2 and SME2: * NEON: - FAMIN - FAMAX * SVE2: - FAMIN_ZPmZ - FAMAX_ZPmZ * SME2: - FAMAX_2Z2Z - FAMIN_2Z2Z - FAMAX_4Z4Z - FAMIN_4Z4Z That is according to this documentation: https://developer.arm.com/documentation/ddi0602/2023-09 Co-authored-by: Caroline Concatto <[email protected]>
