This prologue is not needed any more now that we have the jump table. If optimized code exists, we will not even enter the Liftoff code any more, but instead jump to the optimized code right away. This also allows to remove the {WASM_CODE_TABLE_ENTRY} relocation info kind.

This change adds an addition 2GiB of guard region in front of guarded WebAssembly memories. This provides defense in depth against code generation errors, such as accidental sign extension of a 32-bit value. As we consider supporting 4GiB WebAssembly memories, this is an important line of defense.

This CL adds a builtin which receives an int32 argument and returns the int32 result. Internally, it checks whether the argument is in the valid smi range, then calls the runtime function with the smi argument and converts the return value back from smi to int32. This saves a lot of code in the wasm TF builder and in Liftoff.

This removes error messages about missing _True labels, and instead tries find overloads for the branch protocol and a normal function call at the same time. The branch protocol is only considered if there are _True and _False in the context and the overload returns never. In addition, it prints all macro names of operator overloads if none was matching.

Each local ABT is logically for one page. We passed the space in to the constructor, but this is wrong because the space a page is in can change, e.g. for compaction pages. Instead, pass the page to the local ABT constructor and always get the space from this. To do this we need to push the AllocateLocalTracker() helper and friends down to Page, rather than its superclass MemoryChunk. Unfortunately, we need to keep ReleaseLocalTracker() on MemoryChunk even though only Pages can have local trackers, because we can't do virtual dispatch on MemoryChunk::ReleaseAllocatedMemory() which would allow us to clean up the tracker memory nicely for pages only. We also have to make sure we update external bytes accounting properly when swapping spaces, as in SemiSpace::Swap().

The name {CallerOwnedBuffer} does not make sense in all situations, especially if such an object is returned instead of being passed as argument. I am working on moving the wasm wire bytes off the JS heap, and hence will return unowned references via the API. To prepare this change, I deprecate the existing {CallerOwnedBuffer} and introduce a new {BufferReference} struct with proper field names.

This completes the transition to Assembler::Options, which reduces the assemblers's dependency on isolates, and there is now only one way to create an Assembler, which is to use the options. Note that some operations on assemblers still need an isolate, such as GetCode(), and in these cases, the isolate is an additional argument to the method.

This means we need the original ArrayBuffer object to stay alive until we collect all of the pointers to free (currently done sequentially after marking). We want to move this step to a background task that does not block GC finishing - to do that we need the backing store pointers so that the original page (where the ArrayBuffers live) can be freed.
