The tests keyed vectorization expectations on vect_hw_misalign alone,
but we can and do vectorize the misaligned loop with realigned loads,
so adjust the conditions to also take vect_no_align into account.
Regstrapped on x86_64-linux-gnu, regstrapping on powerpc64le-linux-gnu,
also tested with gcc-15 targeting powerpc-elf. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.dg/vect/vect-strided-a-u8-i2-gap.c: Also take
vect_no_align into account.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
