gcc7-pr79411.patch
Untested fix. In the future we could revert it after making sure all the spots
that can move some SSA_NAME uses would be adjusted and covered by testcases
(create non-(ab) SSA_NAME set to the (ab) one at the original use point and use
it elsewhere), but for now it seems too much work for something rarely used.
