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.
