[stdlib] Switch some shims to use id

Browse Source 
Since ObjC functions take their arguments at +0, we don't need to erase
"object-ness" in order to avoid disturbing reference counts.  This
interacts much better with lifetime optimizations, since the caller must
ensure the argument isn't released until these functions return.
