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).
