Variables with explicit SAVE attribute cannot end up on the stack.
There is no point in checking whether they should be moved off the
stack to static storage.
gcc/fortran/ChangeLog:
PR fortran/98411
* trans-decl.c (gfc_finish_var_decl): Add check for explicit SAVE
attribute.

PR fortran/98411
* gfortran.dg/pr98411.f90: New test.
