vect_recog_mixed_size_cond_pattern dead code now

[Andrew Pinski]

Hi,
  I was reading some code in tree-vect-patterns.cc and I came across
vect_recog_mixed_size_cond_pattern . The code tries to handle
comparisons from COND_EXPR but that cannot happen any more (after
r13-707-g68e0063397ba82).
Should this code be removed now?

Thanks,
Andrew
