Dale Johannesen ce4396bc92 Add CommonLinkage; currently tentative definitions 
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

Anton Korobeynikov 09cfb1cf2d If weak GlobalVariable was bitcast'ed to different type during linking 
we will need to strip all casts for intializer lookup.

Owen Anderson 1f6fbc4bc3 Replace calls of the form V1->setName(V2->getName()) with V1->takeName(V2), 
which is significantly more efficient.

Duncan Sands ad0ea2d430 Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

Chris Lattner 1cc79985cd Fix PR1611 - Visibility should be ignored for a declaration 
when a definition's visibility is different.  Likewise, the
visibility of two declarations mismatching is not an error.

Reid Spencer 3aaaa0b2bd 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.
