chore: add missing noexcepts ( #13370 )
...
swap and move constructors should be noexcept to enable use in STL
containers
A quick inspection suggests that these functions can never throw
exceptions anyway.

feat: optimized division without remainder for Int and Nat ( #8089 )
...
This PR adds optimized division functions for `Int` and `Nat` when the
arguments are known to be divisible (such as when normalizing
rationals). These are backed by the gmp functions `mpz_divexact` and
`mpz_divexact_ui`. See also leanprover-community/batteries#1202 .

feat: add Int16/Int32/Int64 ( #5885 )
...
This adds all fixed width integers with the exception of `ssize_t` so
the code is quick to review as everything just behaves the same.

feat: introduce native functions for Int.ediv / Int.emod ( #3376 )
...
These still need tests, but I thought I'd upstream so I can use
benchmarking and check for build errors.

feat(runtime): increase small nat size
...
In 64-bit machines, the max small nat value should now be (2^63 - 1), and on 32-bit
machines (2^32 - 1).
The main motivation for this modification are the array indexing
operations. With the new representation, if a Nat index is not small,
then it must not be a valid index. This was not true in 64-bit
machines. Example: an array of size 2^33 would fit in memory, and but
an index `i` > 2^32 - 1 would not be a small nat value.

@kha The runtime folder includes what is needed to link a
