Fix PR8720 by printing an error message with a substring that the gcc testsuite searches for. llvm-svn: 121137

Change CodeGenModule to rely on the Module's symbol table instead of shadowing it in the GlobalDeclMap. Eliminates the string-uniquing requirement for mangled names, which should help C++ codegen times a little. Forces us to do string lookups instead of pointer lookups, which might hurt codegen times a little across the board. We'll see how it plays out. Removing the string-uniquing requirement implicitly fixes any bugs like PR6635 which arose from the fact that we had multiple uniquing tables for different kinds of identifiers. llvm-svn: 99012

PR13941: Mark all virtual functions as unnamed_addr. It's not possible to observe their addresses (taking their address gives the vtable slot) so we are free to merge their definitions. llvm-svn: 164864
