There's the `elisp-benchmark` suite in GNU ELPA, but that tests the
execution time to run ELisp code, which I can't imagine can be
significantly affected by your patch.  The other parts that could be
affected could be the time for redisplay or some other primitives that
repeatedly look at things like `BVAR (current_buffer, 
enable_multibyte_characters)`.

Tho, if you patch is careful not to do the "check for `Qunbound`" for
those vars whose buffer_local_flag said -1 (like
`enable_multibyte_characters`), then the risk is even lower.
