[clang] [llvm] Trying to fix undefined symbol error caused by iterator variable (PR #141507)

To expand on what I mean...

For variables which have a strong definition, we usually don't emit them lazily: there's some statement or declaration which is the "definition" point, and we emit the definition as part of visiting that statement or declaration.  This ensures consistency: we consistently emit a definition for things that need a definition.

For variables where the definition isn't necessarily needed, we also have a mechanism for lazily defining them; see DeferredDecls.

I don't want to invent a new way of emitting variable definitions specifically for OpenMP.
