Summary: When using latest clang (3.6 or 3.7/trunck) rocksdb is failing with many errors. Almost all of them are missing override errors. This diff adds missing override keyword. No manual changes. Prerequisites: bear and clang 3.5 build with extra tools ```lang=bash % USE_CLANG=1 bear make all # generate a compilation database http://clang.llvm.org/docs/JSONCompilationDatabase.html % clang-modernize -p . -include . -add-override % make format ``` Test Plan: Make sure all tests are passing. ```lang=bash % #Use default fb code clang. % make check ``` Verify less error and no missing override errors. ```lang=bash % # Have trunk clang present in path. % ROCKSDB_NO_FBCODE=1 CC=clang CXX=clang++ make ``` Reviewers: igor, kradhakrishnan, rven, meyering, sdong Reviewed By: sdong Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D34077
