Hrm, those helpers are not ideally discoverable, partly due to the
system register description for ALLINT not providing any references to
this being a general scheme (which is fixable there) and partly due to
the use of __emit_inst() with a numeric literal - we should probably add
a comment next to the __emit_inst() saying what instruction we are
emitting.
