commit 0363f535e1721362c539bc1462bd7296110c4f15
Author: Pan Li <pan2...@intel.com>
Date:   Thu Jun 12 10:23:49 2025 +0800

    RISC-V: Add test for vec_dup + vmax.vv combine case 1 with max func 0 and 
GR2VR cost 0, 1 and 2
    
    Add asm dump check test for vec_duplicate + vmax.vv combine to vmax.vx,
    with the GR2VR cost is 0, 1 and 2.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i16.c: Add asm check
            for vmax.vx combine.
