variable element

    This patch corrects the virtual token creation for the aggregate constant
    and also corrects tokens for constructor components.

    gcc/m2/ChangeLog:

            PR modula2/114296
            * gm2-compiler/M2ALU.mod (ElementsSolved): Add tokenno parameter.
            Add constant checks and generate error messages.
            (EvalSetValues): Pass tokenno parameter to ElementsSolved.
            * gm2-compiler/M2LexBuf.mod (stop): New procedure.
            (MakeVirtualTok): Call stop if caret = BadTokenNo.
            * gm2-compiler/M2Quads.def (BuildNulExpression): Add tokpos
            parameter.
            (BuildSetStart): Ditto.
            (BuildEmptySet): Ditto.
            (BuildConstructorEnd): Add startpos parameter.
            (BuildTypeForConstructor): Add tokpos parameter.
            * gm2-compiler/M2Quads.mod (BuildNulExpression): Add tokpos
            parameter and push tokpos to the quad stack.
            (BuildSetStart): Add tokpos parameter and push tokpos.
            (BuildSetEnd): Rewrite.
            (BuildEmptySet): Add tokpos parameter and push tokpos with
            the set type.
            (BuildConstructorStart): Pop typepos.
            (BuildConstructorEnd): Add startpos parameter.
            Create valtok from startpos and cbratokpos.
            (BuildTypeForConstructor): Add tokpos parameter.
            * gm2-compiler/M2Range.def (InitAssignmentRangeCheck): Rename
            d to des and e to expr.
            Add destok and exprtok parameters.
            * gm2-compiler/M2Range.mod (InitAssignmentRangeCheck): Rename
            d to des and e to expr.
            Add destok and exprtok parameters.
            Save destok and exprtok into range record.
            (FoldAssignment): Pass exprtok to TryDeclareConstant.
            * gm2-compiler/P3Build.bnf (ComponentValue): Rewrite.
            (Constructor): Rewrite.
            (ConstSetOrQualidentOrFunction): Rewrite.
            (SetOrQualidentOrFunction): Rewrite.
