Tests: Do not use shadow assembly (when using Resharper) for unit tests, not compatible with OSS (Open-Source Signing)
Cecil: Directly use ContainsGenericParameter (not internal anymore)
Compiler: Splitted and improved code that gathers external types/methods (not recursive anymore)
Compiler: Improved hash code of MemberEqualityComparer for better performance.
Compiler: Simplified ResolveGenericsVisitor (should have better performance too).
