One idea would be to get rid of `DWARFDeclContext` and just use `std::vector<CompilerContext>` everywhere. 

We could make a using directive for `std::vector<CompilerContext>` so we don't have to mention the std::vector all of the time :
```
using CompilerDeclContext= std::vector<CompilerContext>;
```
Then we could actually get rid of `DWARFDeclContext` and just use `CompilerDeclContext` everywhere, as it really contains very similar kind of stuff, it is just more DWARF specific. We already make `ConstString` objects for each DIE's name anyway and the comparing many matching entries becomes a pointer compare for the string instead of actual string comparisons.
