Add an SSSE3 implementation of qt_memfill24
Brought to you by the PSHUFB instruction, introduced in SSSE3
(implementation also uses PALIGNR just because we can).
The tail functionality makes use of the fact that the low half of
"mval2" ends in the correct content, so we overwrite up to 8 bytes close
to the end.
