The generic version uses a variable length of u32 registers instead of u32/u64. This allows easier support for "wider" registers without having to rewrite everything. This "generic" version is as fast as the old version in the best case (i == next set bit), and twice as fast in the worst case in 64 bits. Using a macro was chosen over a (forced) inline version because gcc generated more compact code with the macro. The change from (signed) int to unsigned int for i and to_call was intentional as the value can be only between 0 and (width - 1) anyway, and allowed gcc to optimise the code a bit further.
