GCC 7.0 vs. LLVM Clang 4.0 Performance With Both Compiler Updates Coming Soon

GCC 7 and Clang 4 are neck-and-neck for the 7-zip benchmark.

Clang appears to be doing slightly better with the ebizzy workload.

With the timed ImageMagick compilation, Clang is compiling faster than GCC 7.0 and right around the speed of the older GCC 5.4 release.

With the timed PHP compilation test, Clang 4.0 SVN is compiling faster than Clang 3.9.1 and that led to it compiling much quicker than the GNU Compiler Collection.

But GCC still leads over Clang when it comes to the C-Ray test.
