Revert 76c5f27 "Re-land [Debug][CodeView] Emit fully qualified names for globals"
> Before this patch, S_[L|G][THREAD32|DATA32] records were emitted with a simple name, not the fully qualified name (namespace + class scope). > > Differential Revision: https://reviews.llvm.org/D79447 This causes asserts in Chromium builds: CodeViewDebug.cpp:2997: void llvm::CodeViewDebug::emitDebugInfoForUDTs(const std::vector<std::pair<std::string, const DIType *>> &): Assertion `OriginalSize == UDTs.size()' failed. I will follow up on the Phabricator issue.
