    An abstract base superclass for method refs and field refs.

    [author:]

        Marcel Hlopko <marcel.hlopko@fit.cvut.cz>

        Jan Vrany <jan.vrany@fit.cvut.cz>

    [instance variables:]

        classRefIndex ...... index to constant pool to classref describing

                             method's or field's class.

        nameAndTypeIndex ... index to constant pool to name-and-type structure

                             describing name and type of field or name and descriptor

                             of a method.

      !! resolvedClass ...... once a reference is resolved, this slot contains

                             the class to in which this method/field is defined.

                             !!!!!! Used by the VM !!!!!!               

      !! type ............... this slot contains integer of value:

                              - ACX_R_VOID     if method returns void.

                              - ACX_R_DOUBLE   if method returns long / field is of type long

                              - ACX_R_DOUBLE   if method returns double / field is of type double

                              - 0              otherwise.

                             This value is used by both interpreter and JIT compiler to correctly

                             push/pop values onto/from stack. long/double occupies 2 slots (2x 32 bit)

                             !!!!!! Used by the VM !!!!!!
