_mm_movemask_pi8 got removed from stdarch and there is no real alternative (_mm_movemask_epi8 that was suggested here doesn't take a 64bit wide vector but a 128bit vector instead) .

Resolves #288

This has to be done, because `_mm_movemask_pi8` got removed
from stdarch in rust-lang/stdarch#890

I just noticed that there are much more mmx occurrences, but this pr should still make #289 work

This appears to build now! Excellent, thank you.

Fixing that in #292! I think I meant "with two more modifications" at the time but I had just begun the process of hammering away at a million lints.
