    c++: satisfaction value of type typedef to bool [PR95386]

    In the testcase below, the satisfaction value of fn1<int>'s constraint
    is INTEGER_CST '1' of type BOOLEAN_TYPE value_type, which is a typedef
    to the standard boolean_type_node.  But satisfaction_value expects to
    see exactly boolean_true_node or integer_one_node, which this value is
    neither, causing us to trip over the assert therein.

    This patch relaxes satisfaction_value to accept any INTEGER_CST which
    satisfies integer_zerop or integer_onep.

    gcc/cp/ChangeLog:

            PR c++/95386
            * constraint.cc (satisfaction_value): Relax to accept any
            INTEGER_CST that satisfies integer_zerop or integer_onep.
