Added new primitives and bytecodes that support
code generation for XMLambda. All additions are
surrounded by #ifdef XMLAMBDA.

Most important additions:
- Rows (n-tuples) which are implemented on top of Frozen Mutarrays
- Inj (variant sums), which is implemented using a new constructor
called Inj which contains both the value and an unboxed int
which represents the index.
