The jump address is stored in the hash table as (tag & 255 . tag >> 8),
where tag is the tag number from byte-compile-make-tah. The correct address
to jump to is thus calculated in the bytecode VM by car + cdr << 8. Is it
possible to make this calculation in bytecomp.el itself without the risk of
a potential overflow?
