	* DerivedTypes.cs (DerivedType): Implement IsAssignableFrom
	and ContainsGenericParameters

	* DerivedTypes.cs (DerivedType::UnderlyingSystemType): Create
	the unmanaged type before returning so the resulting object is
	understood as a SystemType.

	* DerivedTypes.cs (DerivedType::AssemblyQualifiedName): Return null
	if element's FullName is null as well.

	* DerivedTypes.cs (ArrayType::GetAttributeFlagsImpl): Return proper
	array flags if under compiler context.

	* DerivedTypes.cs (*::FormatName): Return null if elementName is.

	* GenericTypeParameterBuilder.cs: Improve compatibility when not
	under compler context.

	* GenericTypeParameterBuilder.cs (MakeArrayType): Return an instance
	of ArrayType instead of relying on the runtime for it.

	* TypeBuilder.cs: Add error checking to MakeArrayType and remove some
	MonoTODO.

2009-07-14 Rodrigo Kumpera  <[email protected]>

	* DerivedTypesTest.cs: Added tests for generics related
	stuff and interaction with GenericTypeParameterBuilder.

	* GenericTypeParameterBuilderTest.cs: New file with tests
	for the changes done.
