        * trans.h: Remove prototypes for gfor_fndecl_math_exponent4,
        gfor_fndecl_math_exponent8, gfor_fndecl_math_exponent10 and
        gfor_fndecl_math_exponent16.
        * f95-lang.c (build_builtin_fntypes): Add new function types.
        (gfc_init_builtin_functions): Add new builtins for nextafter,
        frexp, ldexp, fabs, scalbn and inf.
        * iresolve.c (gfc_resolve_rrspacing): Don't add hidden arguments.
        (gfc_resolve_scale): Don't convert type of second argument.
        (gfc_resolve_set_exponent): Likewise.
        (gfc_resolve_size): Don't add hidden arguments.
        * trans-decl.c: Remove gfor_fndecl_math_exponent4,
        gfor_fndecl_math_exponent8, gfor_fndecl_math_exponent10 and
        gfor_fndecl_math_exponent16.
        * trans-intrinsic.c (gfc_intrinsic_map): Remove intrinsics
        for scalbn, fraction, nearest, rrspacing, set_exponent and
        spacing.
        (gfc_conv_intrinsic_exponent): Directly call frexp.
        (gfc_conv_intrinsic_fraction, gfc_conv_intrinsic_nearest,
        gfc_conv_intrinsic_spacing, gfc_conv_intrinsic_rrspacing,
        gfc_conv_intrinsic_scale, gfc_conv_intrinsic_set_exponent): New
        functions.
        (gfc_conv_intrinsic_function): Use the new functions above.
