        * fold-const.c (fold <ABS_EXPR>):  Re-fold the result of folding

        always nonnegative from fold to here.  Additionally, cabs and fabs
        are always non-negative, and pow and atan are non-negative if
        their first argument is non-negative.

        * builtins.c (fold_builtin_cabs): New function to fold cabs{,f,l}.
        Evaluate cabs of a constant at compile-time.  Convert cabs of a
        non-complex argument into fabs.  Convert cabs(z) into
        sqrt(z.r*z.r + z.i*z.i) at the tree-level with -ffast-math or
        -funsafe-math-optimizations or -ffast-math.
        (fold_builtin): Convert BUILT_IN_FABS{,F,L} into an ABS_EXPR.
