X86-64 CFLAGS experiments

What impact do they really have?

-fomit-frame-pointer is useless. It adds noise. This might be expected, as the kernel 2.6.9 changelog specifically says frame pointers are not the default on X86-64.

-O3 really is better than -O2 and -O1 (not shown)

-funroll-all-loops -ftracer -fpeel-loops do add a few percent, generally, and don't hurt more than about 1 percent.

Testing -funroll-loops and -funswitch-loops

Here we see there is some difference between -funroll-loops and -funroll-all-loops, plus or minus. No clear win with -funroll-loops, which is somewhat surprising.

-funswitch-loops adds a couple percent noise to the scores, which could be in a margin of error here. Not a clear win but maybe OK.
