Stack-based unmarshaler ( #546 )
...
* Benchmark script
* Rewrite unmarshaler using the stack
Instead of tracking the build chain using `target`s, use the stack
instead.
Working and most benchmarks look good, but regression on structs unmarshalling.
~60% slower on ReferenceFile/struct.
* Shortcut to check if last node of iterator
* Remove unecessary pointer allocation
* Skip over unused keys without marking them as seen
* Add some tests
* Fix mktemp on macos

Playing with an AST
...
Idea would be to build a light AST as a first pass, then have the
unmarshaler and Document parser do what they need with it.
