[vm/compiler] Do not generate unnecessary field length guards GuardFieldLengthInstr::EmitNativeCode aborts background compilation if we're not tracking list length for a field (guarded_list_length() == Field::kNoFixedLength). I'm seeing a lot of aborted background compilations on a Flutter app with the reason "GuardFieldLengthInstr: field state changed while compiling". This CL avoids generating these useless (and harmful) GuardFieldLengthInstr if not tracking list length for a field.
