This commit introduces a comprehensive set of test cases to the RISC-V test suite, specifically targeting register group overlap scenarios for the vwmaccus.vx vector instruction. The tests cover various data types and vector lengths to ensure correct handling of register usage when instructions might share or overlap register resources.
