Ivan Donchevskii efc39304a1 Clang: Move the majority of completion items sorting to ClangBackend 
With this change ClangCodeModel only needs to sort completions by prefix.

Also some other optimization have become possible and are implemented here:
1. Getting completions after '{' for constructor overloads by replacing
   it with '(' inside usaved file.
2. Checking for all overloads requires only previous item check because
   all Class completions are already sorted to go before all CXXConstructor
   completions. Since they are not mixed no extra search is required.
