Reland r312224 - [ItaniumCXXABI] Always use linkonce_odr linkage for RTTI data on MinGW This fixes cases where dynamic classes produced RTTI data with external linkage, producing linker errors about duplicate symbols. This touches code close to what was changed in SVN r244266, but this change doesn't break the tests added in that revision. The previous version had missed to update CodeGenCXX/virt-dtor-key.cpp, which had a behaviour change only when running the testsuite on windows. Differential revision: https://reviews.llvm.org/D37327 llvm-svn: 312306

type_info objects are not unnamed_addr: the ABI requires us to unique them and permits the implementation of dynamic_cast (and anything else which knows it's working with a complete class type) to compare their addresses directly. rdar://16005328 llvm-svn: 201020

Fix for PR5594: use EmitGlobalDefinition instead of EmitCXXDestructor so that we check whether the vtable needs to be generated. llvm-svn: 89984
