Duncan P. N. Exon Smith 0341a8121b IR: Remove MDNodeFwdDecl ... Remove `MDNodeFwdDecl` (as promised in r226481). Aside from API changes, there's no real functionality change here. `MDNode::getTemporary()` now forwards to `MDTuple::getTemporary()`, which returns a tuple with `isTemporary()` equal to true. The main point is that we can now add temporaries of other `MDNode` subclasses, needed for PR22235 (I introduced `MDNodeFwdDecl` in the first place because I didn't recognize this need, and thought they were only needed to handle forward references). A few things left out of (or highlighted by) this commit: - I've had to remove the (few) uses of `std::unique_ptr<>` to deal with temporaries, since the destructor is no longer public. `getTemporary()` should probably return the equivalent of `std::unique_ptr<T, MDNode::deleteTemporary>`. - `MDLocation::getTemporary()` doesn't exist yet (worse, it actually does exist, but does the wrong thing: `MDNode::getTemporary()` is inherited and returns an `MDTuple`). - `MDNode` now only has one subclass, `UniquableMDNode`, and the distinction between them is actually somewhat confusing. I'll fix those up next. llvm-svn: 226501		2015-01-19 20:36:39 +00:00
