ProcType gets turned into WebIDLProcType, so I assume the intention is that they are identical. I changed the definition of WebIDLProcType to match ProcType, and added a static assert to check that they have the same number of cases. I also changed the coercion from a static_cast<> to an explicit switch statement so that it will degrade more gracefully if, say, the enums get reordered, or one enum gets a case added and removed at the same time.
