LLVM Clang 3.2 + GCC 4.8 + LLVM DragonEgg Compilers

Benchmarking LLVM Clang 3.0, 3.1, 3.2 SVN compilers and GCC 4.7/4.8 under Linux with Ubuntu 12.10 x86_64 from an Intel Core i7 Lenovo ThinkPad laptop. Benchmarking by Michael Larabel for a future article on Phoronix.com. Also testing of the LLVM DragonEgg 3.1 / 3.2 SVN plug-in on GCC 4.7.2 as a plug-in for using LLVM's optimizers plus one run of using LLVM DragonEgg SVN while using both the GCC and LLVM optimizers.
