Forgive me but I went ahead and fixed it.  I just figured out that I could
have the code generator output asserts at every divide by a power of two to
check that the results agreed with signed shifts and hence easily caught
all the places where there was a bug.  I've also realised that I can have
the code generator output #if #else #endif code for remapOop:in: and so not
incur any overhead in Spur, which doesn't GC during primitives.
