A program can use `make-arity-wrapper-procedure` to synthesize a
function that reports a given arity mask (without calling `compile`).
In addition, `set-arity-wrapper-procedure!` suports modifying the
implementation of a synthesized procedure. Although similar
functionality could be achieved with `(lambda args (apply (unbox proc)
args))`, an arity wrapper procedure can dispatch to another procedure
without allocating a list for the arguments.
The interpreter now uses an internal variant of arity wrappers to
cooperate with `procedure-arity-mask`.

Revert the use of ephemeron pairs in weak hashtables, since the
difference is visible via guardians. Add hashtable based on ephemerons
(to avoid key-in-value problems) as an explicit variant.

arguments. cp0 optimizes away a number of additional equality
operations at optimize-level 3 (including bytevector=?) when
applied to the same variable references, as it already did for
eq?, eqv?, and equal?, at all optimize levels.
