Hi Mehdi,

I have updated docs/BitSets.rst to hopefully give a clearer explanation of
how bitsets can encode C++ type information. Please take a look and let me
know if this makes more sense to you.

It looks like the HTML documentation at llvm.org isn't updating, so you can
read the document at [1] or just look in the source tree.
