Patch which I am testing

This finishes up the patch. Not much has changed from the previous one except
that I assert that VCE of a SSA_NAME only happens with gimple_p. And a comment
which explains why this needs to be handled seperately. in the commit log about
optimizing the VCE<SSA_NAME> case which is PR 123968.
