This commit introduces a suite of new test cases specifically designed to validate the handling of register group overlap for the RISC-V vector vfwadd.wv instruction. These tests ensure that narrow operands (vs1) do not incorrectly fall within the vs2 register group, covering various floating-point formats and vector lengths.
