Fortran: fix dependency checks for inquiry refs [PR115039]
gcc/fortran/ChangeLog:
PR fortran/115039
* expr.cc (gfc_traverse_expr): An inquiry ref does not constitute
a dependency and cannot collide with a symbol.
gcc/testsuite/ChangeLog:
PR fortran/115039
* gfortran.dg/statement_function_5.f90: New test.
(cherry picked from commit d4974fd22730014e337fd7ec2471945ba8afb00e)
