Detailed Description

Value wrapper in the Metadata hierarchy.

This is a custom value handle that allows other metadata to refer to classes in the Value hierarchy.

Because of full uniquing support, each value is only wrapped by a single ValueAsMetadata object, so the lookup maps are far more efficient than those using ValueHandleBase.

Handle collisions after Value::replaceAllUsesWith().

RAUW isn't supported directly for ValueAsMetadata, but if the wrapped Value gets RAUW'ed and the target already exists, this is used to merge the two metadata nodes.
