`AttributedType` is uniqued based on `attrKind`, but not `attr`. So calling
this function may return a type with a pointer to a different `Attr` (although
of the same kind). Is this a problem? Do we want to fully unique
`AttributedType` based on it's `Attr*`?
The other option I believe is to fetch the `Attr*` from `AttributedTypeLoc`
(which you can get through the `TypeSourceInfo` from `Decl` or
`ExplicitCastExpr`) rather than the `AttributedType`, but doing that for
generic expressions gets quite hairy.
