New Revision: 93209

URL: http://llvm.org/viewvc/llvm-project?rev=93209&view=rev
Log:
CIndex:
- Remove unused (and unimplemented) clang_getDeclarationName().
- Remove unused (and unimplemented) clang_getEntity().
- Add clang_getEntityFromDecl(): maps from a CXDecl to a CXEntity)
- Add clang_getDeclaration(): maps from a (CXEntity, CXTranslationUnit) to a CXDecl).
