[Vm-dev] benchmarking and recent results

I also compared my "brand new" Pharo VM compiled with clang (LLVM 5 or 
whatever it is called, latest in Xcode 5) on Mac with the downloaded Mac 
binary from Eliot (2776) which I presume is... GCC 4.2?

Either way, the results using the bench image was more or less that they 
are within a few % of each other. The largest diff was Eliot's being 
around 10% faster on ... DeltaBlue I think?

But the point is - clang is obviously working!

Thanks Clément for that bench image, so nice with just an image 
sometimes. :)

regards, Göran

PS. I guess one could play the CC flags game indefinitely to find the 
best combo for clang, haven't tried.

PPS. Also tried using GCC 4.8.1 and 4.9, but then the compiled VM throws 
"Bus error: 10" at me. Note that it compiles using the switches for 
clang then... (Esteban and Igor - we need a nice way of switching 
compiler in CMakeVMMaker!)
