Duncan P. N. Exon Smith ae9e15f914 IR: Split GenericMDNode into MDTuple and UniquableMDNode ... Split `GenericMDNode` into two classes (with more descriptive names). - `UniquableMDNode` will be a common subclass for `MDNode`s that are sometimes uniqued like constants, and sometimes 'distinct'. This class gets the (short-lived) RAUW support and related API. - `MDTuple` is the basic tuple that has always been returned by `MDNode::get()`. This is as opposed to more specific nodes to be added soon, which have additional fields, custom assembly syntax, and extra semantics. This class gets the hash-related logic, since other sublcasses of `UniquableMDNode` may need to hash based on other fields. To keep this diff from getting too big, I've added casts to `MDTuple` that won't really scale as new subclasses of `UniquableMDNode` are added, but I'll clean those up incrementally. (No functionality change intended.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225682 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-12 20:09:34 +00:00
