On x86-64 and compiling with -O2 using stdc_leading_zeros compiles to
the bsr instruction. The fls function removed by this patch is inlined
but still loops while checking each bit individually.
* nss/getaddrinfo.c: Include <stdbit.h>.
(fls): Remove function. This function contains a left shift of 31 on an
'int' which is undefined.
(rfc3484_sort): Use stdc_leading_zeros instead of fls.
