[patch, fortran] Bug 71764 - [4.9/5/6/7 Regression] ICE in gfc_trans_structure_assign

[Jerry DeLisle]

This trivial patch removes the problem. As far as I can tell, looking at 
-fdump-tree-original, the results are correct.

Regression tested on x86-64.  I will add a test case from the PR.
I plan to commit to trunk and then backport after about a week if no 
problems show up.

Regards,

Jerry
