Bug Description
In a recent discussion, Paul pointed out that SBCL does not actually
support specialized value cells---with consequences like closed over
bindings declared to be of type FLOAT will still be boxed.
With specialized value cells, it may also be possible to support
ATOM-INCF on appropriately declared lexical bindings.

For value cells, it's all very nicely abstracted out in emit-make- value-cell and with a few calls to value-cell-set/ref in compiler/ ir2tran. lisp.
