Eliminate excessive PCH deserialization caused by the search for __cxxabiv1::__fundamental_type_info in every translation unit. Previously, we would perform name lookup for __cxxabiv1::__fundamental_type_info at the end of IRGen for a each translation unit, to determine whether it was present. If so, we we produce type information for all of the fundamental types. However, this name lookup causes PCH deserialization of a significant part of the translation unit, which has a woeful impact on performance. With this change, we now look at each record type after we've generated its vtable to see if it is __cxxabiv1::__fundamental_type_info. If so, we generate type info for all of the fundamental types. This works because __cxxabiv1::__fundamental_type_info should always have a key function (typically the virtual destructor), that will be defined once in the support library. The fundamental type information will end up there. Fixes <rdar://problem/7840011>. llvm-svn: 100772
