Maybe we could factor this out. There are 3 identical versions of the code above
(flow_graph_compiler_xxx.cc).

                                 \
max_len may be needed by other parts of code. Please factor it out.

Good idea, In an new CL I will factor this into Utils.

I have added TypedData::MaxElements which computes the max elements and used
this everywhere.
