Title: Implement tuple.__add__, dict.__contains__ and builtin id() function

The __contains__ method crashes the runtime when using the 'dict' type directly

eg.
1 in dict() # fails deep down in stl

Also for id() I took the cpython approach by casting the address of the Box* to i64. I noticed thats an llvm type, is that correct?
