Work around dllimport bug with exclude_from_explicit_instantiation.

When dllimport is specified on a class, and
exclude_from_explicit_instatiation is specified on a member, clang-cl
will still expect a definition to be available externally. But this is
not correct.

Surprisingly one one symbol seems to be consistently affected by this
bug. So this patch simply works around it there.
