  glibc: backport AArch64 memcmp improvements

Bug description:
  [impact]

  glibc 2.37 contains a number of improvements to the memcmp routines
  for server-grade AArch64 implementations (in particular, graviton3).
  They should be backported to jammy and focal, as the LTS releases are
  by far the most used on servers.

  [test case]

  TODO

  [Regression potential]

  This could potentially impact performance on other, non-server-grade
  arm64 platforms such as RPi. We'll need to run tests against such
  machines to check impact.
