Now that bug 888600 has landed, we can do this.

The only caller is nsDOMClassInfo::RegisterClassProtos. The only caller of that is nsDOMClassInfo::Init. In nsDOMClassInfo::Init this is called after we have done the RegisterClassName call for "DOMConstructor". Since the only bits of classinfo left are DOMConstructor and DOMPrototype, and both use nsIDOMDOMConstructor as their interface, we call RegisterClassProto with "DOMConstructor" as aClassName, find the existing nsGlobalNameStruct, and return without doing anything. So this entire codepath can be removed. MozReview-Commit-ID: JfXmIex7tLC

We don't resolve it normally, because nsDOMConstructorSH overrides PostCreatePrototype to be a no-op, so nsWindowSH::GlobalResolve never actually defines the relevant property on the window. We also hide it in nsWindowSH::NameStructEnabled. But in the Xray-to-window case we attempt to define it. We shouldn't do that. MozReview-Commit-ID: 3tnMnSQuvuT

We only have classinfo left for DOMConstructor and DOMPrototype, both of which use nsDOMConstructorSH, which overrides PostCreatePrototype. To avoid -Werror build failures, this changeset also removes static functions that were only reachable from PostCreatePrototype. MozReview-Commit-ID: JpJOuMHAAuo

The only caller of nsDOMConstructor::nsDOMConstructor is nsDOMConstructor::Create which has no callers. Also removes the now-unused nsDOMConstructorSH class. MozReview-Commit-ID: GgOO8ugXFKb

Also removes various code that stops compiling this way and static functions that are now unused. MozReview-Commit-ID: KHYxly2c3Id

GetXPCProto is now static and not called, so needs to go too. MozReview-Commit-ID: I6DilDx2e2m
