Ilya Biryukov 5ea158077e Revert "Reland [Modules] Remove unnecessary check when generating name lookup table in ASTWriter"
This reverts commit 67b298f6d82e0b4bb648ac0dabe895e816a77ef1.

We got linker errors with undefined symbols during a compiler release
and tracked it down to this change. I am in the process of understanding
what is happening and getting a reproducer.

Sorry for reverting this again.

I will reopen #61065 until we fix this.
