Herald added projects: clang, LLDB.

This is the final phase of the refactoring towards using llvm::Expected
and llvm::Error in the ASTImporter API.
This involves the following:

- remove old Import functions which returned with a pointer,
- use the Import_New functions (which return with Err or Expected) everywhere and handle their return value
- rename Import_New functions to Import

This affects both Clang and LLDB.
