I'm having trouble telling what I'm looking at.  Could you please flesh out the commit message a bit?  This says it's introducing compiler-rt builtins - but it doesn't link in compiler-rt?  

libc/src/__support/builtins/addtf3.h returns something from fputil into a bulitins namespace, but this doesn't appear builtin?

I need more of a roadmap than I've got here, sorry!
