55e4e98a2a For PR1195: 
Rename PackedType -> VectorType, ConstantPacked -> ConstantVector, and
PackedTyID -> VectorTyID. No functional changes.

70af9b98ec avoid creating a temporary string when reading the symbol table for a 
module.  This speeds up the bcreader 11%.

43d0b955a3 push bytecode decompressor out through APIs. Now the bytecode reader 
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

6af21b3029 For PR411: 
This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

cdaf88ff9d For PR411: 
Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

4effa38086 Replacing std::iostreams with llvm iostreams. Some of these changes involve 
adding a temporary wrapper around the ostream to make it friendly to
functions expecting an LLVM stream. This should be fixed in the future.

f65a8539ec Discard code that supported old bytecode formats. This makes the Bytecode 
Reader code much easier to read and maintain. Backwards compatibility from
version 5 format has been retained. Older formats will produce an error.

f4c7ceebaf Change Path::getStatusInfo to return a boolean and error string on an error 
instead of throwing an exception.  This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

in lib/Bytecode/Archive/Makefile is now removed. One small step closer to
a smaller LLVM.

3bac59d2f0 Fix a problem with llvm-ranlib that (on some platforms) caused the archive 
file to become corrupted due to interactions between mmap'd memory segments
and file descriptors closing. The problem is completely avoiding by using
a third temporary file.
