The problem is that they are used in other builtin types (well, maybe not, but that's a big problem with various pointer types). I will look into getting the lto1 fixups into trunk (ISTR they fix some corner-cases anyway), it should then be easy to experiment with excluding single builtin types from the cache pre-loading.
