Now that our HIR is type clean (yeah!), we no longer have
to conservatively assume F/I and D/J are aliased. This
enables more accurate side effects analysis, with improvements

Refinement:
The HIR is not completely clean between building and SSA.

the on-stack replacement mechanism assumes an order of method
compilation than can sometimes be violated if conditions are just
right.

This change allows compilation requests that were dropped due to
a race condition to eventually be re-issued.  It does this by allowing
the 16-bit hotness counter to wrap around.
