The old bug was about bad code generation, and that was fixed.  I don't think
it needs to be reopened.

I can not find any discussion about fixing this issue in any way other than
forbidding it.

I have no problem with forbidding clobbering fixed registers.  That is a
related but distinct issue.

I do not think it is helpful to force people to consider pic vs. non-pic
issues.  They can still consider them if they choose, but I do not think it is
helpful to force them.
