Move the furniture around some more.
Mostly just moving things around, with minor changes to behavior.
- Instead of walking through all classes twice (once for verification,
once for optimization), we now walk through them once and do both
operations on a given class before moving on to the next.
- If verification and optimization were disabled, the VM used a special
"no fork + exec" path. It adds complexity for little benefit, so
it's gone.
- Reduced the amount of stuff being passed as arguments through multiple
layers of functions. Notably, a pointer to a read-only lookup table
is now accessed via a global.
- The PROFILE_FIELD_ACCESS define now just blocks the quickening of
field accesses instead of blocking all optimizations. (Not sure this
is worth keeping around.)
