Yes, Emacs already has a bitset implementation for its boolean vectors. My vague 
recollection is that the Emacs code could benefit from using a Gnulib 
implementation, and that the new Gnulib bitset implementation would benefit from 
some of the ideas in the Emacs code.

One top-level question is how does memory allocation work? Emacs has its own 
memory allocator, and doesn't want to use plain malloc. It has its own xmalloc 
implementation; will that suffice?
