Running GCC 4.9 With Intel's Core i7 "Core-AVX2"

I've already delivered GCC vs. LLVM Clang compiler benchmarks on Intel's Core i7 4770K "Haswell" platform and tested the "core-avx2" optimizations offered by the latest compilers. That previous testing was done from the stable releases of LLVM Clang 3.1/3.2 and GCC 4.7/4.8 releases, but looking ahead, here's some benchmarks of the latest GCC 4.9 development snapshot.
