Manual backport of #106076 to
release/8.0-staging

## Customer Impact

- [x] Customer reported
- [ ] Found internally

#122057

Silent bad code caused by invalid loop invariant code motion. An error
in tracking memory dependence can allow the JIT to hoist an expression
that is not loop invariant out of a loop.

While customer reported, the issue was found by Fuzzlyn.

The known repro cases require a two-level loop nest, with an expression
that is VN invariant (eg a constant) but memory dependent in the
outerloop sitting below an inner loop.

## Regression

- [ ] Yes
- [X] No 

## Testing

Validated the repro case now passes. The issue was fixed in 9.0, though
the fix had a slightly different form.

## Risk

Low. This make the JIT more conservative about optimizing some
constructs. No SPMI diffs for the 9.0 version of the fix; no SPMI diffs
for libraries with the current fix.

main PR #128775

# Description

Backport of the WASI CI disable from 9.0-staging to 8.0-staging.
`wasm-ld` from wasi-sdk dynamically links `libxml2.so.2`, renamed to
`libxml2.so.16` in Ubuntu 26.04, breaking all WASI CI jobs.

Contributes to #128772

- **`eng/pipelines/runtime.yml`**: Comment out WASI smoke tests and
`simple-wasm-build-tests`
- **`eng/pipelines/extra-platforms/runtime-extra-platforms-wasm.yml`**:
Comment out WASI smoke tests, `simple-wasm-build-tests`, and optional
WASI library tests

# Customer Impact

None. WASI CI is already broken; no runtime behavior changes.

# Regression

Yes — introduced by Ubuntu 26.04 image update (libxml2 soname change).

# Testing

CI-only change. Verified no uncommented `wasi`/`wasi_wasm` references
remain in affected pipeline files.

# Risk

Low. Disabling CI jobs that are already failing. No production code
touched.

# Package authoring signed off?

N/A — no package changes.

Backport of #120546 to release/8.0-staging

/cc @jeffhandley @tarekgh

## Customer Impact

- [ ] Customer reported
- [x] Found internally

This test failed in CI on 9.0:
https://dev.azure.com/dnceng-public/public/_build/results?buildId=1431345&view=ms.vss-test-web.build-test-results-tab&runId=39820274&paneView=debug&resultId=132492.

Since the same test exists on 8.0, I think it should be fixed there as
well.

## Regression

- [ ] Yes
- [x] No

## Testing

Verified in main, and the failing test is occurring in
release/9.0-staging as well.

## Risk

Low. Test only, handling new data.

Pull request overview

Routine forward-merge from release/8.0-staging into release/8.0 bringing in a JIT loop-hoisting fix plus associated regression coverage and a set of test / infrastructure updates for the release branch.

Changes:

  • Fix optRecordLoopMemoryDependence to walk the update loop’s parent chain so memory dependencies are attributed to an ancestor loop when appropriate.
  • Add a new JIT regression test (Runtime_122057) that forces FullOpts (TieredCompilation=0) to validate the loop-hoisting scenario.
  • Update Arcade/runtime-assets dependency versions and adjust CI configuration (WASI/WASM jobs disabled; Helix macOS queues moved to OSX.15; tweak test skips).
