Let's squeeze some more µs when running exported code.
On a simple case run 100k times with a few objects, I go from 1.8s to 1.5s.
The generated exports are also a bit smaller if it matters.
This works by:
- using local variables instead of manually dealing with a stack
- creating more optimized object hydrators for internal classes
This PR also fixes handling of hard references that are bound to external variables.
