Add a pointer to the owning LLVMContext to Module.  This requires threading LLVMContext through a lot
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

emitted or the machine code for a function is freed.  Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change.  I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.

2. The interpreter can delete the ModuleProvider and replace it with
   another so don't depend on it being around after the EE is created.
3. Don't just run llvm_shutdown on exit but actually delete the EE as well.
   This cleans up a vast amount of memory (but not all) that EE retained
   through exit.

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.

pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.
