* TypeBuilderTest.cs: Renamed tests and updated bug number. Enabled
test for UnderlyingSystemType, and improved it. Improved test for
null parent.
* ConstructorOnTypeBuilderInstTest.cs: Enabled test for GetParameters.
* ConstructorBuilderTest.cs: Enabled test for GetParameters. Renamed
test for SetCustomAttribute, and added new tests.
* ModuleBuilderTest.cs: Added tests for bug #387404.
* TypeBuilder.cs: Use Assembly.FullName instead of AssemblyName.
In UnderlyingSystemType, return UnderlyingSystemType of created type
when available. For an enum, UnderlyingSystemType is the type of the
first instance field. If no instance field is available, throw an
InvalidOperationException. Retain original behavior when operating in
compiler context.
* ConstructorBuilder.cs: Moved implementation of GetParameters to
GetParametersInternal to allow it to be used internally when type is
not yet created.
* CustomAttributeBuilder.cs: Added GetParameters method that uses
GetParametersInternal on ConstructorBuilder, and use it where
necessary.
