PathScale EKOPath 5.0 Beta Compiler Performance

Beginning with the HMMer benchmark, the EKOPath 5.0 Beta didn't show any performance improvements over the binaries generated by EKOPath 4.0. The EKOPath compiler suite was still slower than GCC (both 4.7 and 4.8 releases), but PathScale's compiler was faster than LLVM/Clang.

The MAFFT results were similar to HMMer with the PathScale compiler not being as fast as GCC on the Intel Core i7 system but was faster than LLVM/Clang.

PathScale 5.0 was able to generate a working binary for BLAKE2 where PathScale 4.0 couldn't compile a working copy of BLAKE2. However, the performance of PathScale's binary was multiple times slower than GCC and LLVM/Clang.

For SciMark2's Monte Carlo, EKOPath 5.0 was actually faster than GCC 4.7.2 but not as fast as GCC 4.8.0. For this particular test case, LLVM/Clang was even faster than GCC 4.8.0.
