[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.
