[PATCH 2/4]middle-end: lower COND_EXPR into gimple form in vect_recog_bool_pattern

Hi All, Currently the vectorizer cheats when lowering COND_EXPR during bool recog. In the cases where the conditonal is loop invariant or non-boolean it instead converts the operation back into GENERIC and hides much of the operation from the analysis part of the vectorizer. i.e. a ? b : c is
