When building a shared libc++.dll, it pulls in libc++abi.a statically
with the --wholearchive flag. If such a build is done with
--export-all-symbols, it's reasonable to assume that everything
from that library also should be exported with the same rules as normal
local object files, even though we normally avoid autoexporting things
from libc++abi.a in other cases when linking a DLL (user code).

This should fix the build after SVN r316178, which worked fine
on GCC 5.4, but failed on clang with errors like these:
MinGW.h:26:3: error: too few template arguments for class template 'StringSet'
StringSet<> ExcludeSymbols;
^
lld/Common/LLVM.h:28:30: note: template is declared here
template<typename T> class StringSet;
Don't forward declare and add the using directive in the main
lld/Common/LLVM.h header, but just qualify the class name
in MinGW.h instead.
