ef7178406b Reimplement LinkFunctionProtos in terms of GetLinkageResult. This fixes
the second half of link-global-to-func.ll and causes some minor changes in
messages.

There are two TODOs here.  First, this causes a regression in 
2008-07-06-AliasWeakDest.ll, which is now failing (so I xfailed it).  Anton,
I would really appreciate it if you could take a look at this.  It should be
a matter of adding proper alias support to GetLinkageResult, and was probably
already a latent bug that would manifest with globals.

The second todo is to reimplement LinkAlias in the same pattern as 
function and global linking.  This should be pretty straight-forward for 
someone who knows aliases, but isn't a requirement for correctness.

d31cacb5d6 implement linking of globals to functions, in one direction
(replacing a function with a global).  This is needed when building
llvm itself with LTO on darwin, because of the EXPLICIT_SYMBOL hack
in lib/system/DynamicLibrary.cpp.

Implementation of linking the other way will need to wait for a 
cleanup of LinkFunctionProtos.

fa995d7cc5 Factor code to copy global value attributes like
the section or the visibility from one global
value to another: copyAttributesFrom.  This is
particularly useful for duplicating functions:
previously this was done by explicitly copying
each attribute in turn at each place where a
new function was created out of an old one, with
the result that obscure attributes were regularly
forgotten (like the collector or the section).
Hopefully now everything is uniform and nothing
is forgotten.

3602011bec Fix PR1146: parameter attributes are longer part of
the function type, instead they belong to functions

056b656f99 Improve error handling in the linker by:
1. Eliminate redundant error messages. LinkInFile and LinkInArchive

   telling the user again that an item couldn't be linked in.

2. Improve the formatting of error messages (separating content).

   it clear that the file is being ignored.

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.
