      Description

        In .ad files, it is difficult to have register classes that depend on runtime conditions. JDK-7090968 partially solves the problem, but it does not work in cases when not only a register mask, but also a
        "stack mask" is generated for a register class (i.e., the register class is "cisc-spillable").

        The goal of this enhancement is to extend ADLC parsing to support register classes that depend on dynamic conditions, including cisc-spillable classes.
