Workaround -fno-frontend-optimize.

* frontend-passes.c: Include opts.h.
(optimize_comparison): Renamed from optimize_equality.
Change second argument to operation to be compared.
Use flag_finite_math_only to avoid comparing REAL and
COMPLEX only when NANs are honored. Simplify comparing
of string concatenations where left or right operands are
equal. Simplify all comparison operations, based on the result
of gfc_dep_compare_expr.
* dependency.c: Include arith.h.
(gfc_are_identical_variables): Volatile variables should not
compare equal to themselves.
(gfc_dep_compare_expr): Handle string constants and string
concatenations.
