  -----------
  Provide cmake test if alignment requirement is strict

This is based on AX_CHECK_ALIGNED_ACCESS_REQUIRED from autoconf-archive.

Note, that on some arches unaligned access behavior could be changed at
runtime via prctl(1). Also, unaligned memory access is still slower (and
very slow on some arches) even if it's not strictly required.

(cherry picked from commit d2810d23a9f30ae885f9bf0783f0847a12972ff3)
