This handles everything except movdi, which is more complex.
One perhaps non-obvious thing is the use of the ABI as an "isa"
entry with respect to the loading of an address constant. This
appears in movsi for VMS. This turns out to be significantly
easier than using two different attributes to control "enabled"
and I couldn't think of a better name than "isa".
