Implement __declspec(selectany) under -fms-extensions
...
selectany only applies to externally visible global variables. It has
the effect of making the data weak_odr.
The MSDN docs suggest that unused definitions can only be dropped at
linktime, so Clang uses weak instead of linkonce. MSVC optimizes away
references to constant selectany data, so it must assume that there is
only one definition, hence weak_odr.

g++.abi/vtable3a.C among others. It also caused failures in the libc++
test suite.
