In https://crrev.com/c/2645694 we push the full q registers before lazy compile, but we did not change the fixed frame size to account for the wider registers being pushed. This manifested in the frame having data like: (gdb) x/10xg start.ptr_ 0x7f5576ff3eb0: 0x0000000000000000 0x0000336b08202759 0x7f5576ff3ec0: 0x7ff000007f801000 0x0000000000000000 0x7f5576ff3ed0: 0x7ff000007f801001 0x0000000000000000 0x7f5576ff3ee0: 0x7ff000007f801002 0x0000000000000000 0x7f5576ff3ef0: 0x7ff000007f801003 0x0000000000000000 The GC then walks part of this frame, thinking that 0x7ff000007f801003 is a heap object, and then crashes. Add some static_asserts (similar to builtins-x64) to remind ourselves that the pushed registers have to match the size in frame constants.

This adds a regression test for https://crrev.com/c/2652488. The test reduces the available code space such that it would trigger an OOM condition if code is not garbage-collected. In order to guarantee garbage-collection in all configurations, an explicit interrupt check is added to the WasmDebugBreak runtime function.

Actual FeedbackVector IC slots don't participate in the Ref class, since they are read during serialization as we process bytecode. So FeedbackVectorRef really only deals with the FeedbackCell array and the SharedFunctionInfo. These two types are already in the no serialized list, so it's pretty easy to move this class over there too.

We were doing the cache lookup using the original {wire_bytes_vec}, but then inserting the module with another copy stored in the {NativeModule}. This causes {NativeModuleCache::Key::operator<} to do a full {memcmp} on the two wire bytes copies. By using the same pointer consistently, we can avoid that costly {memcmp}.

Tolerance was set to 50 microseconds. This is not enough and causes flaky failures. Tolerance is needed because we record milliseconds and an empty scope can still take a few milliseconds to create and destroy. Increasing the tolerance to 500 microseconds should suffice and makes sense for the test. All expected values are in 10s of milliseconds, so half a millisecond tolerance should be reasonable.

Insertion into the map is expensive, hence avoid inserting every single code object. Instead, collect them in a {std::vector}, and only insert them when the {owned_code_} map is being used. By sorting the vector before inserting into the map, we can make most insertions constant time instead of logarithmic in the size of the map, by using the previous insert position as a hint for the next one. Drive-by: Remove an unneeded {WasmCodeRefScope}.

Fix 1: Track Scope::needs_home_object and Scope::uses_super_property accurately. When "eval" is seen, figure out whether it can access "super" and if yes, set the corresponding home object as needed. Fix 2: The object literal scope shouldn't be entered for things inside spreads. Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275 Previous reland: https://chromium-review.googlesource.com/c/v8/v8/+/2637220 This saves memory (the home object doesn't need to be stored for each method, but only once per class) and hopefully makes the home object a constant in the optimized code.

1) Wasm code is not associated with a Code object, hence WasmFrame::unchecked_code will always return a null object. Hence we can use the default implementation from TypedFrame and avoid the lookup on the heap which will always fail. 2) InternalFrame inherits from TypedFrame, hence can also reuse the unchecked_code implementation from TypedFrame. 3) Use "{}" instead of "Code()" to return "nothing".
