This should have been
#ifdef HAVE_AVX2
pad = 32;
#else
pad = 16;
#endif

Use the same PSHUFB-based matching as in the SSSE3 helper, just 2x

Directly use the new helper if __AVX2__ is defined. It makes the other
helpers unused, so mark them inline to prevent warnings.
Rewrite and simplify init_vectorized_lexer.
