Subject: Reapply "IntrusiveRefCntPtr -> std::shared_ptr for
 CompilerInvocationBase and CodeCompleteConsumer"

Aleksey Shlypanikov pointed out my mistake in migrating an explicit
unique_ptr to auto - I was expecting the function returned a unique_ptr,
but instead it returned a raw pointer - introducing a leak.

Thanks Aleksey!

This reapplies r291184, reverted in r291249.
