This is not needed to fix https://github.com/llvm/llvm-project/issues/126536 (https://github.com/llvm/llvm-project/pull/126689 does that), it's a hedge against additional bugs that may be lurking that cause infinite loops.

I'm open to suggestions as to whether this is a good idea. It may hide some bugs, but the symptoms of those bugs are much less severe (incorrect or failed heuristic resolution of a dependent name in a template) than an infinite loop.
