New Revision: 188569

URL: http://llvm.org/viewvc/llvm-project?rev=188569&view=rev
Log:
Introduce the clangIDE library.

Libclang has a lot of functionality that is inaccessible.
The purpose of clangIDE is to move most of the functionality of libclang to it so we
can expose it and have libclang be more of a thin C wrapper over clangIDE.

Start by moving the USR generation functionality into clangIDE.
