	Isn't the question whether the new allocator can replace reload,
or at least most of it?  If the new allocator can replace the part of
reload which crashes in this type of case, there is not problem.

	MPY-ADD allocation seems more like carefully obeying the register
classes as opposed to a constant that cannot be loaded directly or a value
ending up in completely the wrong register which requires secondary and
tertiary reloads to fix up.
