Tail Call optimizations

[Horcrux7]

The Java JIT can optimize the code to use Tail Calls. WebAssembly does not have such a JIT. That this optimizing must occur on compile time. In our case in JWebAssembly because the Java Byte code does not contains Tail Call information.

The Tail Call feature of WebAssembly should be in phase 4 before implementing. https://github.com/WebAssembly/proposals

This is a placeholder ticket for future features.
