Finally fix prefetch on Linux It was due to a missing -msse compiler option ! Without this option the CPU silently discards prefetcht2 instructions during execution. Also added a (gcc documented) hack to prevent Intel compiler to optimize away the prefetches. Special thanks to Heinz for testing and suggesting improvments. And for Jim for testing icc on Windows.
