Revert #67745 "[asan] Ensure __asan_register_elf_globals is called in COMDAT asan.module_ctor (#67745)"

This reverts commit 1a4b9b6f73391d94f4f96cc964cbf89cfdd59b5b.

When getUniqueModuleId(&M) is empty, we may add comdat to internal constants
like $.str, causing spurious `error: relocation refers to a symbol in a
discarded section` lld errors.
