[D-runtime] druntime commit, revision 414

[Steve Schveighoffer]

Notes:

One thing I didn't mention is that I fixed a performance issue WRT thread local 
static constructors.  The issue is that the algorithm to detect cycles was being 
run every time a thread was created, but the moduleinfo data is static -- you 
only need to try and detect cycles once.  So I changed the way TLS constructors 
are called to follow the order as laid out in the dtor array (was already being 
constructed anyways).

Fawzi, you may want to incorporate this in Tango, the current algorithm to 
detect cycles will not detect certain cycles (as evidenced by a cycle existing 
for a long time undetected in phobos 2).  It's also nice to have the cycle 
printed out :)
