Automatically adding ccs based on suspected regression changelists: [wasm] Add checks and trace info for lazy compilation on native heap by kimanh@google.com - https://chromium.googlesource.com/v8/v8/+/f9d2c0daa36397d3a0f53dc5701bb5ae10aa7572 If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label.

Hooray, Kim's new checks caught a bug :) We knew that there are bugs if the function table is exported and then modified, and that's exactly what the generated test case does. Lowering priority, as this requires the '--wasm-lazy-compilation' runtime flag. No security implications, as lazy compilation is disabled for wasm code.
