ada730740b Implement support for a new LLVM 1.3 bytecode format, which uses uint's 
to index into structure types and allows arbitrary 32- and 64-bit integer
types to index into sequential types.

b25ac02112 Remove a bunch of cruft that was used to be backwards compatible with the last 
prerelease format for LLVM bytecode files.  Now we only are compatible with
LLVM 1.0+.

4ca49f84ba Use the true, decoded name of the archive member in getObjectType. 
In ReadArchiveBuffer, make sure that MemberName is set in the case where
getObjectType would want to return SVR4LongFilename.

2258355dda 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
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.

cce1db873e If these blocks are empty, there is no reason to even emit the bytecode blocks.

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.

accd21042c Do not bother to emit a BytecodeBlock for an empty symbol table. This commonly 
occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.
