    [gdb/testsuite] Add KFAIL for missing support of reverse-debugging of vmovd
    
    On my openSUSE Leap 15.1 system I run into:
    ...
    (gdb) PASS: gdb.reverse/step-precsave.exp: turn on process record
    break 76^M
    Breakpoint 2 at 0x400654: file step-reverse.c, line 76.^M
    (gdb) PASS: gdb.reverse/step-precsave.exp: breakpoint at end of main
    continue^M
    Continuing.^M
    Process record does not support instruction 0xc5 at address 0x7ffff783fc70.^M
    Process record: failed to record execution log.^M
    ^M
    Program stopped.^M
    0x00007ffff783fc70 in __memset_avx2_unaligned_erms () from /lib64/libc.so.6^M
    (gdb) FAIL: gdb.reverse/step-precsave.exp: run to end of main
    ...
    
    The problem is that the vmovd instruction is not supported in
    reverse-debugging (PR record/23188).
    
    Add a KFAIL for this PR.
    
    Tested on x86_64-linux.
