Title: IMPORTANT: Fix vm cvm gc

This fix the current default config of Theano that could have in some case as consequence bad results if this happen with inplace op. The bug caused duplicate computation. If duplicate computation happen on inplace op, this could lead to wrong results.

I didn't finish running all the tests, but I'm highly confident that this is not worst that what is currently in the trunk. So can someone merge it fast?
