No, it doesn't. The change I am proposing removes the unique handling
of condition state registers, and treats them like other registers.
The unique handling of condition state registers is historical, and
arose because of the characteristics of the initial gcc targets (e.g.,
vax, m68k).
The idea to do this is not mine; for more background see the
discussion of cc0 here:
