Summary: There were a few places where MSVC's implicit truncation warnings were getting triggered, which was causing the MSVC build to fail due to warnings being treated as errors. This resolves the issues by making the truncations in some places explicit, and by making it so there are no truncations of literals. Fixes #3239 Supersedes #3259 Closes https://github.com/facebook/rocksdb/pull/3273 Reviewed By: yiwu-arbug Differential Revision: D6569204 Pulled By: Orvid fbshipit-source-id: c188cf1cf98d9acb6d94b71875041cc81f8ff088
