224fdc7a78 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.

ad61772c72 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.

874f9caf13 feat(library/init/control/state): modify monad_run instance for state_t 
@Kha, I was having to use `(run ...).1` in many places
in my code. So, I changed the instance
```
instance (σ m out) [monad_run out m] : monad_run (λ α, σ → out (α × σ)) (state_t σ m) :=
⟨λ α x, run ∘ (λ σ, x.run σ)⟩
```
to
```
instance (σ : Type u) (m out : Type u → Type v) [functor m] [monad_run out m] : monad_run (λ α, σ → out α) (state_t σ m) :=
⟨λ α x, run ∘ (λ σ, prod.fst <$> (x.run σ))⟩
```
If we want to get the resultant state in an action `act`, we can just
use `run (act >> get) init_state`.

af4f831a9f feat(library/init/data/hashmap): hash function produces an uint32 instead of nat 
Most efficient hash functions use uint32/uint64 and produce values
that do not fit in out small nat representation. Thus, GMP big numbers
would have to be created.

4d6cbf62a2 refactor(library/init/lean/parser/parser): we don't need to store the whole message in ok_eps 
In the original parsec paper, they store messages in OK silent/epsilon
results too. This is not necessary, we only need the "expected" field
for the `ok_eps` constructor.
