Creates a label with the {@link Label#FLAG_DEBUG_ONLY} flag set, if there is no already
existing label for the given bytecode offset (otherwise does nothing). The label is created
with a call to {@link #readLabel}.

@param bytecodeOffset a bytecode offset in a method.
@param labels the already created labels, indexed by their offset.
