feat: UIntX.pow and Pow UIntX Nat instances ( #7886 )
...
This PR adds `UIntX.pow` and `Pow UIntX Nat` instances, and similarly
for signed fixed-width integers. These are currently only the naive
implementation, and will need to be subsequently replaced via
`@[extern]` with fast implementations (tracked at #7887 ).

fix: Repr instance for Int32 ( #7467 )
...
This PR fixes the `Repr Int32` instance, which was previously repeating
the `Repr Int16` instance due to a copy-and-paste error.

feat: IntX theory for simprocs and bv_decide ( #7259 )
...
This PR contains theorems about `IntX` that are required for `bv_decide`
and the `IntX` simprocs.
A more comprehensive set of theorems about `IntX` will be part of future
PRs.

feat: IntX.abs ( #7131 )
...
This PR adds `IntX.abs` functions. These are specified by `BitVec.abs`,
so they map `IntX.minValue` to `IntX.minValue`, similar to Rust's
`i8::abs`. In the future we might also have versions which take values
in `UIntX` and/or `Nat`.

This PR adds functions `IntX.ofIntLE`, `IntX.ofIntTruncate`, which are
analogous to the unsigned counterparts `UIntX.ofNatLT` and
`UInt.ofNatTruncate`.
