fact "profitable" to do so.  This makes compactification "free" for small
programs (ie, it is completely disabled) and even helps large programs by
not having to encode pointless compactification planes.

On 176.gcc, this saves 50K from the bytecode file, which is, alas only
a couple percent.

This concludes my head bashing against the bytecode format, at least for
now.

This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by
about 167K, a 25% reduction.  There is still a lot of room for improvement in
the encoding of the compaction table.

return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

intended to save size (and does on small programs), but on big programs it
actually increases the size of the program slightly.  The deal is that many
functions end up using the characters that the string contained, and the
characters are no longer in the global constant table, so they have to be
emitted in function specific constant pools.

This pessimization will be fixed in subsequent patches.
