The assumption behind this optimization was invalid. Even if the string's prototype is unchanged, the symbol could exist somewhere further up the prototype chain. GetProperty has been sped up significantly so it might be fine to just skip this fast path. An alternative would be to use a protector cell.

This CL refactors the existing trap handler code for Linux to allow a cleaner extension to Windows. 1) The CL extracts platform-specific code into separate files, see https://docs.google.com/document/d/1HCgKIpdjy_CEodTLvZ5VuykDI6gGTHrTtau2j0zwm28. Specifically this means: * Move posix-specific API functions from v8.h to v8-wasm-trap-handler-posix.h. Deprecate the existing TryHandleSignal API function. * Move posix-specific function declarations from trap-handler-internal.h to handler-inside-posix.h * Move posix-specific function definitions from handler-shared.cc to handler-outside-posix.cc 2) The CL changes filenames from *-linux.* to *-posix.*. I expect that most of the implementation for MacOS will be the same as for Linux.

This adds support for Promise.all() to --async-stack-traces (also at zero cost, since we can derive the relevant information from the resolve element closure and context). In case of `Promise.all(a)` the stack trace even tells you which element of `a` is responsible, for example ```js async function fine() {} async function thrower() { await fine(); throw new Error(); } async function test() { await Promise.all([fine(), thrower()]); } ``` will generate the following stack trace ``` Error at thrower (something.js:1:9) at async Promise.all (index 1) at async test (something.js:3:3) ``` so it not only shows the async Promise.all() frames, but even tells the user exactly that the second element of `[fine(), thrower()]` is the relevant one.

Currently, because the source float_64_array has an iterator, it hits the code in the "check_iterator" section of TypedArrayFrom which calls IterableToList. This builds a temporary PACKED_ELEMENTS array (and boxes all of the numeric values as HeapNumbers), then uses this as the source array. This patch checks if the source array is a TypedArray, and if the iterator is the built-in one (where we know the iterator's behaviour). If both are true then it bypasses the creation of this temporary array and uses the original TypedArray as the source. This allows it to take advantage of the existing fast code for copying one typed array to another.

This test was incidentally fixed by https://chromium-review.googlesource.com/c/v8/v8/+/1280436. Calls to StartTickSample() and FinishTickSample() are not permitted by multiple producers. If the signal handler interrupts the main thread, both might receive the same pointer into the circular buffer and one will overwrite the data of the other. This means we cannot call it in tests, and have to use AddSample() instead.

Move fixing up Filler objects after deserialization from the StartupDeserializer to the ReadOnlyDeserializer since that's what deserializes the Filler maps. Since only RO_SPACE can contain such objects, skip iterating over all the spaces and just fix them up directly in RO_SPACE. To this end, the PagedSpace code is moved to ReadOnlySpace and the Heap fix up method is removed.

Port e893eb14 Original Commit Message: This adds support for having reference type values (i.e. anyref) stored in an exception. It is the natural combination of the reference type proposal and the exception handling proposal. Note that this also introduces support for having write barriers in generated WasmCode, as this is the first time we are storing references within generated code. Such write barriers will be needed for other uses of reference types (e.g. mutable global) regardless.
