[patch] except.c nothrow_function_p() walks INSN_LIST chain wrong

In the same analysis as yesterday's patch to varasm.c, we have a 
similar piece of code that
passes an INSN_LIST rtx to a function that will reject anything that 
isn't an INSN.

This is clearly wrong (and different from all other walks of the 
without the patch.

I don't have a g++ compiler for my port with delay slots, but the 
SPARC does and today it
looks like a bootstrap  actually is working with the latest mainline sources.
