Since the vector_subscript testcase seems indeed to be frontend issue triggered
by -fipa-pta (and soon by modref). I wonder if we should have fortran bug
tracking this or change component here?

The fortran fail can be reduced to the following with -O1 -fipa-pta, not
sure what goes wrong. It looks like part of the
a (idx (10:6:-2)) = b (idx (10:6:-2))
stores are wrongly elided.

Remaining regressions compared to GCC 8 when running the testsuite with

are
+FAIL: gfortran.fortran-torture/execute/contained_3.f90 execution, -O1
there is also one progression
