    i386: Remove constraints when used with constant integer predicates, take 2

    const_int_operand and other const*_operand predicates do not need
    constraints when the constraint is inherited from the range of
    constant integer predicate.  Remove the constraint in case all
    alternatives use the same inherited constraint.

    However, when there are operands, commitative with a non-constant
    operand, the operand effectively matches e.g.
    nonimmediate_operand|const_int_operand rather than just
    const_int_operand.  We should keep the constraint for
    const_int_operand that are in a % pair. See PR 105624.
