Fortran: Fix deprecate warning with parameter
Only warn with !GCC$ ATTRIBUTES DEPRECATED if
deprecated PARMETERS are actually used.
gcc/fortran/ChangeLog:
* resolve.c (resolve_values): Only show
deprecated warning if attr.referenced.
gcc/testsuite/ChangeLog:
* gfortran.dg/attr_deprecated-2.f90: New test.
