LLVM Clang 3.1 SVN On Core i7 AVX

Testing of LLVM/Clang 3.0 and LLVM/Clang 3.1 development snapshot. Testing from Intel Core i7 3960X Sandy Bridge Extreme Edition CPU under Ubuntu 11.10 x86_64 with the Linux 3.2 kernel. In particular looking towards the Intel Sandy Bridge, Intel Ivy Bridge, and Intel Haswell improvements within LLVM/Clang compilers for a future article on Phoronix.com under Michael Larabel. Testing with the test profile defaults.
