The `PreferedType` should actually already be set in the `ResultsBuilder` (line 
3715). In thoery, `Results.getCompletionContext()` should work fine here as 
well, but it would break some Index tests - it introduced some inconsistency in 
sema scoring when running with and without result caching 
(https://github.com/llvm-mirror/clang/blob/master/test/Index/complete-exprs.c#L35).
 This is probably a bug, but I'm not sure if I'm the right person to chase it 
:(
