Soon, yes.  This change is just moving functions from one header to 
another.  Doing a move + significant change is painful to review... but 
you can see some of where that is going in this now-defunct review:
http://reviews.llvm.org/D17146

I fully intend on making each of the fallback functions call one of the 
uselocale RAII objects.  I would need to ensure that the RAII object 
inlined away on platforms without extended locale support.
