Robert Clausecker ee8b0c436d lib/libc/string: replace ffs/fls implementations with clang builtins ... Most architectures we support (except for riscv64) have instructions to compute these functions very quickly. Replace old code with the ffs and clz builtin functions, allowing clang to generate good code for all architectures. As a consequence, toss out arm and i386 ffs() implementations.
