tree-ssa-uninit: suppress more spurious warnings
* tree-ssa-uninit.c (value_sat_pred_p): This new function is a wrapper
around is_value_included_in that knows how to handle BIT_AND_EXPR.
(is_pred_expr_subset_of): Use the new function. Handle more cases where
code1 == EQ_EXPR and where code1 == BIT_AND_EXPR and thus fix some false
positives.
