binaryen: update to 112.

v112
----

- Add AbstractTypeRefining pass (#5461)
- Add a mechanism to skip a pass by name (#5448)
- Add TypeMerging pass (#5321)
- Add TypeSSA pass  (#5299)
- Optimization sequences like `-O3 -Os` now do the expected thing and run `-O3`
  followed by `-Os`. Previously the last of them set the defaults that were used
  by all executions, so `-O3 -Os` was equivalent to `-Os -Os`. (There is no
  change to the default optimization level that other passes can see. For
  example, `--precompute-propagate -O2 -O1` will run `--precompute-propagate`
  at opt level `1`, as the global default is set to `2` and then overridden to
  `1`. The only change is that the passes run by `-O2` will actually run `-O2`
  now, while before they'd use the global default which made them do `-O1`.)
- Add `--closed-world` flag. This enables more optimizations in GC mode as it
  lets us assume that we can change types inside the module.
- The isorecursive WasmGC type system (i.e. --hybrid) is now the default to
  match the spec and the old default equirecursive (i.e. --structural) system
  has been removed.
- `ref.is_func`, `ref.is_data`, and `ref.is_i31` have been removed from the C
  and JS APIs and `RefIs` has been replaced with `RefIsNull`.
- Types `Data` and `Dataref` have been replaced with types `Struct` and
  `Structref` in the C and JS APIs.
* `BinaryenStringNew` now takes an additional last argument, `try_`, indicating
  whether the instruction is one of `string.new_utf8_try` respectively
  `string.new_utf8_array_try`.
* `BinaryenStringEq` now takes an additional second argument, `op`, that is
  either `BinaryenStringEqEqual()` if the instruction is `string.eq` or
  `BinaryenStringEqCompare()` if the instruction is `string.compare`.
