This commit introduces intrinsic support for the RISC-V Zvabd (Vector Absolute Difference) extension. It resolves an ICE (Internal Compiler Error) that occurred during intrinsic emission by adopting a vwmacc-like pattern. This change ensures correct intrinsic generation and better reflects the Zvabd extension’s semantics.
