runtime: compute size classes statically
No point in computing this info on startup.
Compute it at build time.
This lets us spend more time computing & checking the size classes.
Improve the div magic for rounding to the start of an object.
We can now use 32-bit multiplies & shifts, which should help
32-bit platforms.
The static data is <1KB.
The actual size classes are not changed by this CL.
