TypeReference.Resolve can cause a NRE when a TypeSpecification is created with
a null TypeReference.
This occurs for both FunctionPointerType and PointerType (I hit both cases but
I did not look for others).
This can be duplicated by running Gendarme on
https://bugzilla.novell.com/attachment.cgi?id=353658 from bug
https://bugzilla.novell.com/show_bug.cgi?id=582823
This can be fixed with the following patch.
diff --git a/Mono.Cecil/TypeSpecification.cs b/Mono.Cecil/TypeSpecification.c
