5fc855775d Add support for reading bytecode files with compactiontables for bytecode files. 
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.

630c3ddea0 Bytecode format for LLVM 1.2 no longer explicitly encodes zeros in primitive 
type planes.  This saves about 5k on 176.gcc, and is needed for a subsequent
patch of mine I'm working on.

c5d5cc7b8f Revision of Brian's threading support library to be a bit more generic and 
platform independent.  This code is completely untested (but never used),
and needs autoconf support for detecting pthreads, but it's a start, and
deletes two emails from my inbox.  :)

44232deeda 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)

844284aabe 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.

ed98fd7216 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.

106bba1e9b 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.
