Add an SSSE3 version that uses palignr to align.
Instead of using a non-SIMD method for aligning, we instead load more bytes
from p1 and use the PALIGNR instruction to realign to what we want.
The result is that it's bit slower than the non-SIMD comparison, due to the
complexity. For strings over 8 QChars wide, it's only slightly worse than
the non-SIMD comparison.
