The commit introduces the implementation of the FMUL (floating-point multiply) instruction for the Scalable Matrix Extension (SME) on AArch64. It includes both multi-vector floating-point multiply by vector and multi-vector floating-point multiply variants. New intrinsics corresponding to these instructions have been added, enhancing the capabilities for streaming floating-point operations. This addition enables optimized code generation for SME-based computations.
