    i386/testsuite: Correct res_ref2 array size for avx512bw-vpmov{,us}wb-2.c
    
    Both of the tests under 128 bit are raising:
    
    warning: writing 16 bytes into a region of size 8 [-Wstringop-overflow=]
    
    when compiling, leading to a test fail. The warning is caused by the
    incorrect array size for res_ref2. The wrong size caused the overflow.
    
    Correct them in this patch to fix the test fail.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/avx512bw-vpmovuswb-2.c: Correct res_ref2
            array size.
            * gcc.target/i386/avx512bw-vpmovwb-2.c: Ditto.
