Possible this is actually a WebKit regression between 302054@main and 302102@main.

If it's a WebKit regression, our choices would be: 302098@main (2c1627d7931b) [JSC] Clean up operationWasmToJSExitMarshalArguments and operationWasmToJSExitMarshalReturnValues https://bugs.webkit.org/show_bug.cgi?id=301413 rdar://163321475 302074@main (874cd3bb87fb) [JSC] Remove unnecessary `inline` from `WeakGCSet` constructor and destructor https://bugs.webkit.org/show_bug.cgi?id=301400 302073@main (6c5c02f67319) [JSC] Use error-throwing operations for wasm error-throwing operations https://bugs.webkit.org/show_bug.cgi?id=301374 rdar://162587506 302068@main (db97275cee41) [JSC] Check SAB maxByteLength against MAX_ARRAY_BUFFER_SIZE 302067@main (7e9dff0fcda4) [JSC] Avoid using `MarkedArgumentBuffer` in `createTuple` https://bugs.webkit.org/show_bug.cgi?id=301078 302065@main (9f7337aa62ef) [JSC] Add explicit type constraints to FTL `vmCall` template arguments https://bugs.webkit.org/show_bug.cgi?id=301269

This is not a WebKit regression. clang regression which failed to compile `CLoop::execute` with a small frame size. But given that clang is not aiming at compiling it in a small frame with O0, then we should just skip a test.
