refactor(library/init/lean/ir): platform dependent IR
...
Motivation: in 64-bit machines, we can store boxed uint32 values as a
tagged pointer. In 32-bit machines, we need to allocated an object (like
Haskell) to store the uint32 value. So, the generated bytecode is quite
different in each platform.
This change also allow us to simplify the IR. Example: we don't need the
type `sizet` anymore.
Impact: To be able to bootstrap in both platforms,
we will have to store two versions of the generated code: 32 and 64
versions. In principle, we only need to store the 64-bit version,
and use cross-compilation to build the 32-bit version.

feat(library/init/lean/ir): add is_null
...
We will use this instruction for compiling inductive datatypes such as
`option A` where `A` is represented as an `object`.
In this case, we can represent `some a` as `a` (without any extra memory
allocation), and `none` as the null pointer.
