C++: Cleanup LookupContext

Browse Source 
Since the cache is now more reliable, some workarounds and optimizations
in the instantiation process are not needed anymore.

Also avoid instantiation of base classes when expandTemplates is
disabled.

As a bonus, we now resolve decltype of template function for a type that is not
referenced anywhere but in the decltype.
