That is only documenting LLVM's support for constraints, and this is only
modifying clang's support.

There are (still) no docs on what constraints clang supports (it's often
the same as LLVM's support, but not always. It's really quite unfortunate
how much of the information about what the constraints mean is duplicated
in clang; it'd be nice to clean that up at some point...)
