This is mostly similar to `i16` that I added recently in #15464, but there are some differences: * Some adjustments were needed to support unsigned integers * Add overflow checking of literals, since it's easy to over/underflow when using `u8` due to limited range * Rename primitive integer types from `int16` to `i16` (etc.) to match the user-visible types (needed to get some error messages consistent, and it's generally nicer) * Overall make things a bit more consistent * Actually update `mypy_extensions` stubs This is an unsigned type to make it easier to work with binary/bytes data. The item values for `bytes` are unsigned 8-bit values, in particular. This type will become much more useful once we support packed arrays. --------- Co-authored-by: Shantanu <[email protected]>

The
i16type behaves the same asi64andi32, but is obviously smaller. The PR is big, but it's mostly because of test cases, which are adapted fromi32test cases.Also fix error handling in unboxing of native int and float types (i.e. all types with overlapping error values).
