My questions:
1) Is it OK to put a more general bsf/bsr in druntime or in
Phobos? (if Phobos: in which package to put it?)
IMO I want a std.integer package for such functions.
I started writing one but I have to rewrite it.
I don't know if building up such a package by piecemeal would be
accepted.
2) Is the current sign-extend up to size_t's width really
intended behavior?
It's due to integer promotions, so it should only influence bsr
(when it is called with a signed type.)
