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)

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.

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.
