Log:
[Basic] Update CMakeLists.txt to handle repo
Summary:
The find_first_existing_file and find_first_existing_vc_file macros in
lib/Basic/CMakeLists.txt are removed. The macros are also defined in
{LLVM}/cmake/modules/AddLLVM.cmake for the same purpose. This change
serves the following 2 objectives:
1. To remove the redundant code in clang to use the same
macros in llvm,
2. The macros in AddLLVM.cmake can also handle repo for
displaying correct version information.
