When more than one Module is imported into the same context, such as during an LTO build before linking the modules, ODR type uniquing may cause types to point to a different CU. This check does not make sense in this case. This fixes the error reported in PR34944. https://bugs.llvm.org/show_bug.cgi?id=34944 rdar://problem/34940685 This reapplies a cleaner implementation of r316049. llvm-svn: 316052
