Changes: - Add optional WasmModuleObject field to WasmGlobalObject - Introduce DynamicTypeCheckRef. Use it to typecheck imported global objects. - Correctly typecheck imported WasmGlobalObjects. - Add some testing infrastructure and one test file Bug: v8:7748 Change-Id: Icc62d378d17696c5808d580f1ec84186c9556ec1 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2403248 Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> Cr-Commit-Position: refs/heads/master@{#69872}
