Log:
    PR tree-optimization/50596
    * tree-vectorizer.h (vect_is_simple_cond): New prototype.
    (NUM_PATTERNS): Change to 6.
    * tree-vect-patterns.c (vect_recog_mixed_size_cond_pattern): New
    function.
    (vect_vect_recog_func_ptrs): Add vect_recog_mixed_size_cond_pattern.
    (vect_mark_pattern_stmts): Don't create stmt_vinfo for def_stmt
    if it already has one, and don't set STMT_VINFO_VECTYPE in it
    if it is already set.
    * tree-vect-stmts.c (vect_mark_stmts_to_be_vectorized): Handle
    COND_EXPR in pattern stmts.
    (vect_is_simple_cond): No longer static.

    * lib/target-supports.exp (check_effective_target_vect_cond_mixed):
    New.
    * gcc.dg/vect/vect-cond-8.c: New test.
