1. MAINT: Mark npy_memchr with no_sanitize("alignment") on clang …

   Clangs sanitizer reports unaligned access here, which is correct
   but intentional.  It may well be that the code would be better of
   trying to avoid this unaligned access (and rather vectorizing harder).
   
   But, this is a bit of a tricky choice, since we have to optimize for
   different use-cases (in particular very short scans may be interesting).
   
   So changing this would best be done together with some more careful
   benchmarks.
   
   See also numpygh-21117, which introduced manual loop unrolling to avoid the
   unaligned access.
   
   Closes numpygh-21116
