The attached patch does that, and fixes the problem without
invalidating the information for all the loops.  Thanks for the
suggestion.  I'm going to test this later on.  I still have two
problems with autopar on amd64-linux for getting the spec2006 working
without crashing the compiler.  These are in expand to RTL, in
epxr.c:3366, and in explow.c:621.  I'm still trying to figure out
how to fix these two.
