Differential Revision: https://phabricator.services.mozilla.com/D212554 - - - - - ff246121 by Jan de Mooij at 2024-07-09T16:34:28+02:00 Bug 1902983 - Don't use bailout data after iterating Wasm frames. a=RyanVM

This is similar to bug 1900523, but the fix there was incomplete because the `JSJitToWasm` frame type is only used when we go through the Wasm JIT entry trampoline. Ion can also call Wasm functions directly and in that case the type will be `FrameType::Exit`.
