* gcc-interface/Make-lang.in: Remove ttypef.ads
* checks.adb: Use Machine_Mantissa_Value and Machine_Radix_Value instead
of Machine_Mantissa and Machine_Radix.
* cstand.adb (P_Float_Range): Directly print the Type_Low_Bound and
Type_High_Bound of the type, instead of choosing constants from Ttypef.
(Set_Float_Bounds): Compute the bounds based on Machine_Radix_Value,
Machine_Emax_Value and Machine_Mantissa_Value instead of special-casing
each type.
* einfo.ads (Machine_Emax_Value, Machine_Emin_Value,
Machine_Mantissa_Value, Machine_Radix_Value, Model_Emin_Value,
Model_Epsilon_Value, Model_Mantissa_Value, Model_Small_Value,
Safe_Emax_Value, Safe_First_Value, Safe_Last_Value): Add new
synthesized floating point attributes.
* einfo.adb (Float_Rep): Determine the kind of floating point
representation used for a given type.
(Machine_Emax_Value, Machine_Emin_Value, Machine_Mantissa_Value,
Machine_Radix_Value): Implement based on Float_Rep_Kind of a type and
the number of digits in the type.
(Model_Emin_Value, Model_Epsilon_Value, Model_Mantissa_Value,
Model_Small_Value, Safe_Emax_Value, Safe_First_Value, Safe_Last_Value):
Implement new synthesized floating point attributes based on the various
machine attributes.
* eval_fat.ads: Remove Machine_Mantissa and Machine_Radix.
* eval_fat.adb (Machine_Mantissa, Machine_Radix): Remove. Use the
Machine_Mantissa_Value and Machine_Radix_Value functions instead.
* exp_vfpt.adb (VAXFF_Digits, VAXDF_Digits, VAXFG_Digits): Define local
constants, instead of using constants from Ttypef.
* gnat_rm.texi: Reword comments referencing Ttypef.
* sem_attr.ads: Reword comment referencing Ttypef.
* sem_attr.adb (Float_Attribute_Universal_Integer,
Float_Attribute_Universal_Real): Remove.
(Attribute_Machine_Emax, Attribute_Machine_Emin,
Attribute_Machine_Mantissa, Attribute_Model_Epsilon,
Attribute_Model_Mantissa, Attribute_Model_Small, Attribute_Safe_Emax,
Attribute_Safe_First, Attribute_Safe_Last, Model_Small_Value): Use
attributes in Einfo instead of Float_Attribute_Universal_Real and
Float_Attribute_Universal_Integer and all explicit constants.
* sem_util.ads, sem_util.adb (Real_Convert): Remove.
* sem_vfpt.adb (VAXDF_Digits, VAXFF_Digits, VAXGF_Digits, IEEEL_Digits,
IEEES_Digits): New local constants, in order to remove dependency on
Ttypef.
* tbuild.ads (Make_Float_Literal): New function.
* tbuild.adb (Make_Float_Literal): New function to create a new
N_Real_Literal, constructing it as simple as possible for best
output of constants in -gnatS.
* ttypef.ads: Remove.
