Old patch

Hello,

the code in tree-vect-generic.c to handle vector operations not provided by the
target doesn't know VEC_COND_EXPR. That didn't matter when the vectorizer was
the only producer, but front-ends are going to produce them as well any day
now.

Attaching the patch I was using when experimenting, but IIRC it wasn't in a
state for submission, and its assumption that the first argument can't be an
SSA_NAME or a constant is now wrong.
