reimplement __sync_* builtins to be variadic and to follow the same

semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)
