This is basically the option of replicating GCC-style emutls in
druntime. This is quite simple to implement and you don't even need
special pinning, as the Thread instance object in core.thread can refer
to the TLS array.

This solution can't be implemented in libgcc though, as obviously the
GC is not always available to allocate the arrays in pure C programs ;-)
