Call it a design flaw.

There are two kinds of scratch registers allocated by reload that
serve distinct purposes.  Ports used them interchangably, leading
to bug fixes for things that weren't bugs, leading to a mess that
will be hard to untangle.

That's probably an oversimplification; I don't recall all of the
details at the moment.  It probably wasn't realized from the start
that the two classes of scratches were in fact distinct.

Yes.  We do this for Alpha as well.
