This is necessary to make the new PEImageAnnotationsReader.*WOW64 tests fail
without the fixed code, because otherwise it (normally) just reads a 0 dword for
the top half of the pointer when reading from the x86 process, so everything
works fine.

But it's ugly, so up to you if you think it's valuable or just confusing to have
here.
