When we create a new elements array we should initialize it with holes. The capacity of the newly created elements array could be greater than the actual length of the array and we expect the unused slots to be filled with holes.

This cleans up several parts of the tiering logic. 1) Instead of using the {ExecutionTier} to specify whether we do tier up or down, we introduce a new {TieringState} enum and use that consistently (also where a {bool} was used before). 2) When tiering up or tiering down, always recompile all functions. It's very unlikely that we can reuse previous code anyway (tiering down is cheap enough to just always do it, and when tiering up we need to recompile everything anyway). 3) Remove the {WasmEngine::RecompileAllFunctions} method and inline the implementation into callers. 4) Drive-by: Remove some obsolete comments and fix or extend others.

On-heap TypedArrays have empty ArrayBuffers that are not supposed to be accessed directly. Such ArrayBuffers materialize properly when accessed via their TypedArrays. The queryObjects() sidesteps the bottleneck and finds empty ArrayBuffers by iterating the heap. When preview TypedArrays are constructed for the found ArrayBuffers, they get nullptr data pointers. This CL converts all on-heap TypedArrays into off-heap TypedArrays in queryObjects to make sure that all found ArrayBuffers are valid.

Andreas Haas authored
The existing interface assumed that for atomic binop instructions, the value register and the result register are the same. However, for x64, this assumption is not always useful, and for platforms like arm, this assumption is even negative. The existing interface was originally introduced because ia32 lacks registers, and we wanted to avoid platform-specific code in liftoff-compiler.cc. However, by now the lack of registers on ia32 required us to use platform-specific code also in other places, so we can also use it for atomic binops and thereby enable a better code generation.

To avoid shrinking the unregister token map on each pop of the cleared cell list, the Torque implementation of the cleanup loop avoids shrinking the map until the end of the loop. To support that, PopClearedCellHoldings is refactored to the Torque PopClearedCell which calls the JSFinalization::RemoveCellFromUnregisterTokenMap and the runtime ShrinkFinalizationRegistryUnregisterTokenMap. The former cannot GC is and is implemented in CSA as a fast C call. The latter can GC and is a runtime call. This also incidentally makes uses of FinalizationRegistry without unregister token a fast path that doesn't have to leave Torque.

Sometimes we were triggering a wasm code GC at a time where all native modules just died. Thus, no isolates took part in that GC, and it never finished (because no isolate would ever call {ReportLiveCodeForGC}). This never-ending GC would then block all other GCs for the rest of the life of this wasm engine. This CL fixes this by just finishing the GC immediately if no isolates are outstanding.

Soft-deopt for mono/polymorphic property accesses that don't have any maps, and only allow zero-map feedback to be monomorphic. This makes sure we only emit a megamorphic LoadIC builtin call if the IC was actually megamorphic. JSGenericLowering assumed that zero maps meant that a load site is megamorphic. However, it can be the case that the call-site is monomorphic or polymorphic, and the maps had died. In this case we don't want to call the megamorphic IC builtin, as on a stub cache miss we fallback to a normal LoadIC miss, which can record mono/polymorphic feedback in the IC. After this, we'll enter a miss loop in the megamorphic load builtin, and worse the LoadIC assumes that there's something "wrong" with the feedback, so it'll keep trying to reconfigure the handler (possibly allocating new load handlers if this is a prototype field access). As a drive-by, rewrite GetRelevantReceiverMaps to be an in-place filtering of the maps rather than copying them.

In strict mode stores to non-existent properties throw. We should not install a handler with the property cell for such stores. These handlers would expect that the value exists when they see a property cell. If this property cell gets invalidated later, it appears as if it is a valid property cell with undefined value. This leads to an incorrect behaviour. This cl checks if we are in strict mode and uses a slow stub in such cases.
