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.

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.

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.
