[fpc-pascal] type constraints in generics?

I don't think it's currently supported. It will be, if someone is willing to
do it.

To the best of my knowledge, FPC generics are based on C++ one, while C# one
seems to be coming from Java. FPC one is simply hold as a macro by the
compiler when it's declared and written with all generic types resolved when
it's specialized. It's all done at compile time. In C# case, it's the
runtime environment who is responsible for this. That's why C# one is more
dynamic.
