clang-format (https://reviews.llvm.org/D33932) to keep primary headers at the top and handle new utility headers like 'gmock' consistently with other utility headers. No other change was made. I did no manual edits, all of this is clang-format. This should allow other changes to have more clear and focused diffs, and is especially motivated by moving some headers into more focused libraries. llvm-svn: 304786
