The definitions were a bit of a mess and there wasn't even a fall back to __builtin_clz() on compilers supporting it. Now we instead define a macro for each implementation that is set on an arch-dependent case by case, and add the fall back ones only when not defined. This also allows the flsnz8() to automatically fall back to the 32-bit arch-specific version if available. This shows a consistent 33% speedup on arm for strings. This is cbtree commit c6075742e8d0a6924e7183d44bd93dec20ca8049. This is ebtree commit f452d0f83eca72f6c3484ccb138d341ed6fd27ed.
