[PATCH] D31802: Add methods to find the next *unset* bits in a bit vector

[Adrian McCarthy via Phabricator via llvm-commits]

amccarth added a comment.

Not really in the scope of this change, but, since BitVector has these STL-like methods, 'twould be nice if there were a BitVector::npos analogous to std::basic_string::npos rather than having all the users of the class have to hardcode the magic value or make vague checks like `>= 0`.

I realize that these methods are returning an `int` rather than a `size_type` like the corresponding methods on strings.  Still, magic sentinel values are magic sentinel values, and the usage would be more consistent.
