Allow bound simplification of array subreferences.
gcc/fortran/ * simplify.c (simplify_bound_dim): Tighten the check for array fullness by also checking for absence of subreference. (simplify_bound): Don't skip simplification if the array has subreferences. (simplify_cobound): Same. gcc/testsuite/ * gfortran.dg/bound_simplification_4.f90: New. From-SVN: r222681
