            Bug ID: 30807
           Summary: Process record does not support instruction 0x62
                    (AVX512)

This is basically the same as this:

https://sourceware.org/bugzilla/show_bug.cgi?id=3D23188

... but for AVX512.  I'm seeing this when running gdb.reverse/step-precsave=
.exp
on a CPU with AVX512 support (AMD EPYC 9634) on Debian 12 (bookworm):

      continue^M
      Continuing.^M
      Process record does not support instruction bound.^M
      Process record does not support instruction 0x62 at address
0x7ffff7f49b40.^M
      Process record: failed to record execution log.^M
      ^M
      Program stopped.^M
      0x00007ffff7f49b40 in ?? () from /lib/x86_64-linux-gnu/libc.so.6^M
      (gdb) FAIL: gdb.reverse/step-precsave.exp: run to end of main
