GCC 7.0 vs. 6.3 vs. 5.4 vs. 4.9 Compiler Benchmarks On Linux x86_64

With GCC7 feature development ending, this week I conducted some benchmarks of the latest GCC 7 snapshot against that of the past three major release series of the GNU Compiler Collection: 6.3.0, 5.4.0, and 4.9.4. All tests were done on Ubuntu Linux x86_64 with an Intel Core i7 6800K processor.
