Patch in testing
Hi,
I am testing the attached patch. It also plugs symmetric problem on varpool.
The cycle testing code in varasm I was mentioning is used for weakrefs only.
Porbably that checks could go, but I would preffer to wait for 4.8. There are
too many changes in 4.7 concerning aliases already.
