count-leading-zeros: use a lookup table on non-gcc compilers While this only affects non-gcc compilers, we can assume that lookups are faster than conditionals, even if it results in a slightly larger executable size. * lib/count-leading-zeros.h (count_leading_zeros_32): Use an alternate implementation, suggested by Jim Meyering.
