199560c668 Make several cleanups to Andrews varargs change: 
1. Pass Value*'s into lowering methods so that the proper pointers can be

2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
   into any load/stores from the valist that are emitted

The issue is there is no unsigned -> double conversion, only signed.  So I

this should be in a different BB, but in the mean time, I use a branch
