Track malloc size with a header for SHOW_MEMORY

Track initializedness of Node memory more precisely
...
By not initializing Node members with dummy default values.
This has performance/code size benefits, and improves debugging when
running under valgrind.
Unfortunately this also makes it easy to write code that uses
uninitialized memory, so if valgrind doesn't have good coverage then we
might let some uninit usages sneak through.
We plan to have good coverage for valgrind, so I think it's ok. If
writing correct code becomes too tedious then we can go back to
initializing Node fields with dummy default values.

My understanding is that this it's now UB for any value that's not
listed to inhabit Type, so the gcc warning about control reaching the
end of a function with an exhaustive switch where every case returns
should go away now.
