Helper class to manipulate !mmra metadata nodes.

This can be visualized as a set of "tags", with each tag representing a particular property of an instruction, as explained in the MemoryModelRelaxationAnnotations docs.

This class (and the optimizer in general) does not reason about the exact nature of the tags and the properties they imply. It just sees the metadata as a collection of tags, which are a prefix/suffix pair of strings.
