* Allow AddRange to work with int64_t. Fixes #516 Also, tweak how we manage per-test build needs, and create a standard _gtest suffix for googletest to differentiate from non-googletest tests. I also ran clang-format on the files that I changed (but not the benchmark include or main src as they have too many clang-format issues). * Add benchmark_gtest to cmake * Set(Items|Bytes)Processed now take int64_t
