LC0068 not triggering without record variable

[jwikman]

LC0068 does not fire inside table code that does not use record variables.

Repro: Add below code to a table:

    procedure MyProcedure()
    begin
        Rec.Modify(); // <-- This do trigger LC0068
        Modify(); // <-- This do NOT trigger LC0068
        this.Modify(); // <-- This do NOT trigger LC0068
    end;
