I'm afraid this can't be done in the combiner nor in peephole2 and generally
would be hard to do after expansion, but perhaps it could be done during
expansion or earlier, by folding the (complex) sequence into a new builtin,
preferrably with space in the name to make it inaccessible to users and then
expanding that builtin.
