Replace the former AST walking interpreter implementation with a single pass
bytecode compiler and a corresponding virtual machine.
The rewrite lays the groundwork for a couple of improvements with will be
subsequently implemented:
- Ability to precompile ucode sources into binary byte code
- Strippable debug information
- Reduced runtime memory usage

Promote the use of `let` to move ucode examples closer to ES syntax.

Do not emit dummy T_ASSIGN nodes for plain variable declarations without
initialization (`let foo` or `local foo`).
This also allows simplifying `ut_check_for_in()` since we only need to
deal with one common structure for both `for (... in ...)` and
`for (local ... in ...)` cases.
