Ryan Scott 049096c506 Support building with GHC 9.0
This contains a variety of fixes needed to make the packages in the `macaw`
repo compile with GHC 9.0:

* GHC 9.0 implements simplified subsumption (see
  [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.0?version_id=5fcd0a50e0872efb3c38a32db140506da8310d87#simplified-subsumption)).
  In most cases, adapting to this is a matter of manually eta expanding
  definitions, such as in `base:Data.Macaw.Analysis.RegisterUse`. In the case
  of `macaw-x86-symbolic:Data.Macaw.X86.Crucible`, the type signature of
  `evalExt` had to be made more specific to adapt to the loss of contravariance
  when typechecking `(->)`.
* GHC's constraint solver now solves constraints in each top-level group
  sooner (see
  [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.0?version_id=5fcd0a50e0872efb3c38a32db140506da8310d87#the-order-of-th-splices-is-more-important)).
  This affects `macaw-aarch32` and `macaw-symbolic`, as they separate top-level
  groups with `$(return [])` Template Haskell splices. The previous locations
  of these splices made it so that the TH-generated instances in that package
  were not available to any code before the splice, resulting in type errors
  when compiled with GHC 9.0.

  To overcome this, I rearranged the TH-generated instances so that they appear
  before the top-level groups that make use of them.
* GHC 9.0 now enables `-Wstar-is-type` in `-Wall`, so this patch replaces some
  uses of `*` with `Data.Kind.Type`. `Data.Kind` requires the use of GHC 8.0 or
  later, so this patch also updates thes lower bounds on `base` to `>= 4.9` in
  the appropriate `.cabal` files. (I'm fairly certain that this requirement was
  already present implicity, but better to be explicit about it.)
* The `asl-translator`, `crucible`, and `semmc` submodules were updated to
  allow them to build with GHC 9.0. The `llvm-pretty` and
  `llvm-pretty-bc-parser` submodules were also bumped to accommodate unrelated
  changes in `crucible` that were brought in.
* The upper version bounds on `doctest` in `macaw-symbolic`'s test suite were
  raised to allow it to build with GHC 9.0.
