[D-runtime] druntime fixes again break Windows DLL support

[Don Clugston]

I've also had problems with DLLs in the git version of druntime.
When I use Runtime.initialize() in a thread, in a DLL which was
dynamically loaded, it crashes. I haven't traced into it, but it feels
like exactly the same behaviour I saw when TLS wasn't initialized.
Almost as if something in the runtime is using a TLS variable before
initialization has happened.

I also notice that the docs in 2.052 had an inconsistency: the first
example used dll_helper, the later ones use Runtime.initialize().
