68e3dbc493 Major changes. Now we only compactify individual type planes if it is in
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.

cf3e67f70a Add support for writing bytecode files with compactiontables for bytecode files.
This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by

the encoding of the compaction table.

7be08bfae1 ConstantPointerRef's are no longer emitted. This saves 20028 bytes in the
bytecode files when compiling 176.gcc, but more importantly will make it
easier to eliminate CPR's in the future (no new .bc revision will be
required to support them)

933619912b Allow bytecode files to refer directly to global values as constants, instead
of forcing them to go through ConstantPointerRef's.  This allows bytecode
files to mirror .ll files, allows more efficient encoding, and makes it easier
to eventually eliminate CPR's.

7969dc2bec Change all of the bytecode reader primitives to throw exceptions instead of
returning error codes.  Because they don't return an error code, they can
return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

Also eliminate the special case code for little endian machines.

83bb3d2f4e The new bytecode format supports emitting strings a special case. This is
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.

8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter.
Since this really only makes sense for these two, change hte instance variable

reasonable to add bcwriter specific stuff to it as necessary.
