Joerg Sonnenberger 4695f91f43 When using a symbol with attribute weakref, search for it first and 
don't try the normal GetOrCreateLLVM. The latter could drop the weak
atrtibute on the second reference, if there is no explicit declaration
of the aliasee.

Rafael Espindola da1826102f really fix 6473 by handling weakref in constant expressions.

Rafael Espindola 6a836706c4 Fix PR6473. 
Clang's support for weakref is now better than llvm-gcc's :-)

We don't introduce a new symbol and we correctly mark undefined references weak only if there is no
definition or regular undefined references in the same file.
