	The big constants rewrite
	Fix #75746, #75685 and more
	As a side effect saved 1MB for MWF ;-)
	
	* attribute.cs (GetAttributeArgumentExpression): Use ToType, GetTypedValue.
	(GetMarshal, GetMethodImplOptions, GetLayoutKindValue): Values are not
	enum based for corlib compilation.
	
	* cfold.cs (BinaryFold): Convert operand for enum additions. Fixed enum
	subtractions.
	
	* class.cs (FixedField.Define): Use ResolveAsConstant.
	
	* const.cs (IConstant): Interface constants and enums.
	(Const.ResolveValue): New method for constant resolvning.
	(ExternalConstant): Constants from imported assemblies.
	
	* constant.cs (Constant.GetTypedValue): Used to get constant with forced
	conversion; like enums.
	(Constant.ToType): Converts this constant to different type.
	(Constant.Increment): Adds 1.
	
	* convert.cs (ImplicitConversionRequired): Simplified.
	
	* cs-parser.jay: Create EnumMember directly.
	
	* decl.cs (MemberCore.CheckObsoleteness): Checks for ObsoleteAttribute presence.
	
	* doc.cs (GenerateEnumDocComment): Removed.
	
	* ecore.cs (Expression.ResolveAsConstant): New constant specific method.
	(ConvertIntLiteral): Removed.
	(FieldExpr.ResolveMemberAccess): Refactored to remove constant specific if(s).
	
	* enum.cs (EnumMember): Implement IConstant.
	(Enum.IsValidEnumConstant): Removed.
	(Enum.GetNextDefaultValue): Removed.
	(Enum.FindMembers): Updated.
	(Enum.GenerateDocComment): Iterate enum members.
	
	* expression.cs (Cast.TryReduce): Handle enums correctly.
	(New.Constantify): Made public.
	(MemberAccess.DoResolve): Removed contant specific if(s).
	
	* literal.cs (NullLiteral): Implement new abstract methods.
	
	* statement.cs (GotoCase.Resolve): Use new constant methods.
	(SwitchLabel.ResolveAndReduce): Use new constant methods.
	
	* typemanager.cs (LookupEnum): Removed.
	(IsEnumType): Fixed to work with corlib.
	(RegisterConstant): Removed.
	(LookupConstant): Removed.
	(GetConstant): Changed to work with IConstant.
