Say something like this POC:
We have those already, see ctz_hwi, clz_hwi etc.
The thing is that BITMAP_WORD isn't always the same type as unsigned
HOST_WIDE_INT, and so we need ones with the BITMAP_WORD type.
That sounds like a problem overloading would solve to the benefit
of all clients. I.e., overload count_trailing_zeros (or whatever
other name) to take integer arguments of all widths (signed and
unsigned) and call the appropriate built-in from each. That way
we just have to remember one function name and know that it will
be the right choice regardless of the type of the argument.
