with optimized clang, still with optimized gcc, both with -O1



Remade clang with make ENABLE_OPTIMIZED=1.  Clang times improved a lot.



Now, the degradation of relative performance of gcc w.r.t. clang

is more dramatic.



Still, gcc does better at low LAST_LESS, but reaches break even

at lower LAST_LESS (about 8).
