Orvid King b4d88d7128 Fix the build with MSVC 2017 
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
