Log:
    PR tree-optimization/50650
    * tree-vect-patterns.c (vect_recog_mixed_size_cond_pattern): Don't
    call vect_is_simple_cond here, instead fail if cond_expr isn't
    COMPARISON_CLASS_P or if get_vectype_for_scalar_type returns NULL
    for cond_expr's first operand.
    * tree-vect-stmts.c (vect_is_simple_cond): Static again.
    * tree-vectorizer.h (vect_is_simple_cond): Remove prototype.

    * gcc.c-torture/compile/pr50650.c: New test.
