Zhiguang:
  Please add more information on macro __FILE_NAME__. This is new macro supported by CLANG compiler. 

Thanks

Subject: [PATCH] MdePkg DebugLib: Enable FILE NAME as DEBUG ASSERT for CLANG

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1548
This change will make the generated image not include the absolute file path.
If so, the generated debug image can be reproduced in the different root directory. Also, it will reduce the size of debug image size.
