    * internal-fn.c: Include diagnostic-core.h.
    (expand_BUILTIN_EXPECT): New function.
    * gimplify.c (gimplify_call_expr): Use false instead of FALSE.
    (gimplify_modify_expr): Gimplify 3 argument __builtin_expect into
    IFN_BUILTIN_EXPECT call instead of __builtin_expect builtin call.
    * ipa-inline-analysis.c (find_foldable_builtin_expect): Handle
    IFN_BUILTIN_EXPECT.
    * predict.c (expr_expected_value_1): Handle IFN_BUILTIN_EXPECT.
    Revert 3 argument __builtin_expect code.
    (strip_predict_hints): Handle IFN_BUILTIN_EXPECT.
    * gimple-fold.c (gimple_fold_call): Likewise.
    * tree.h (fold_builtin_expect): New prototype.
    * builtins.c (build_builtin_expect_predicate): Add predictor
    argument, if non-NULL, create 3 argument __builtin_expect.
    (fold_builtin_expect): No longer static.  Add ARG2 argument,
    pass it through to build_builtin_expect_predicate.
    (fold_builtin_2): Adjust caller.
    (fold_builtin_3): Handle BUILT_IN_EXPECT.
    * internal-fn.def (BUILTIN_EXPECT): New.

    * trans.c (gfc_unlikely, gfc_likely): Don't add __builtin_expect
    if !optimize.
