This gives almost 30x compile-time speedup on ImagingGaussianBlurOnce. Based on profiling with Observatory, it seems to be a performance bug in how hash codes are stored on objects. The majority of time is spent in Object_GetHash, which does not compute a hash, but looks it up in a weak hash table in the VM.
