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.
