* string.c (search_nonascii): unroll and use ntz
* configure.in (__builtin_ctz): check.
* configure.in (__builtin_ctzll): check.
* internal.h (rb_popcount32): defined for ntz_int32.
it can use __builtin_popcount but this function is not used on
GCC environment because it uses __builtin_ctz.
When another function uses this, using __builtin_popcount
should be re-considered.
* internal.h (rb_popcount64): ditto.
* internal.h (ntz_int32): defined for ntz_intptr.
* internal.h (ntz_int64): defined for ntz_intptr.
* internal.h (ntz_intptr): defined as ntz for uintptr_t.
