Simplify/clean up debug info suppression in CodeGenFunction

CodeGenFunction is run on only one function - a new object is made for
each new function. I would add an assertion/flag to this effect, but
there's an exception: ObjC properties involve emitting helper functions
that are all emitted by the same CodeGenFunction object, so such a check
is not possible/correct.

Consumed analyis: Renamed *PStatus to *PInfo.
The change was made for readability, as the PropagationInfo objects don't
always contain a status.  This is submitted as a separate patch because it
touches a lot of lines and I don't want it cluttering up the next patch.
