[PATCH] D104119: [IR] Remove forward declaration of GraphTraits from Type.h

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

> though might be worth considering #including "GraphTraits.h" rather than the forward declaration - makes maintenance a bit easier later on, if default template arguments were added to GraphTraits or other changes are made.

I considered and rejected it. I think the LLVM project as a whole prefers forward declarations to #includes, for the sake of build time.
