This CL implements https://github.com/tc39/proposal-top-level-await/pull/159, which reached consensus at the March 2021 TC39. The high-level intent is for parent modules that depend on async modules to remember the DFS post-order such that when their async dependency finishes, they execute in that original post-order. This aligns the ordering between completely sync module graphs and async module graphs.

The initial implementation of {FixedSizeSignature} contains undefined behaviour, because {InitReps} wrote to the {reps_} array before the constructor of that array has been called. This also resulted in bugs if {FixedSizeSignature} was used with types that actually have a constructor (like {ValueType}). The array constructor would call the default constructor on each contained element, thus overwriting the values written by {InitReps}. This CL fixes that by switching to a plain array, and only writing to the array in the body of the constructor (after the field was properly initialized). It also removes the {Concat} method in favor or simply copying from two input arrays in a private constructor. Drive-by: Use proper constant names for the template parameters to make cpplint happy.

The `Script::source_url` field holds the value of the magic `//# sourceURL` comment if found, and the `Script::name` field is supposed to hold the actual name of the resource (as provided by the embedder ideally), in case of Chromium that's supposed to be the URL (in case of Node.js it's often the local path). Using `source_url` worked by chance so far, but for loading DWARF symbol files correctly we need the initiator (which we pick from the embedderName of the Script as reported to DevTools). More importantly, the partial handling of `//# sourceURL` in V8 is a layering violation and causes trouble in DevTools, i.e. when users put relative paths here. So as part of refactoring and correctifying the handling of `//# sourceURL`, we need to make sure that the embedder provided name (the URL in case of Chromium) is always stored in the `Script::name` field.

This use of LR previously allowed overwriting it with arbitrary addresses that aren't signed. Change this so we never return to an arbitrary LR. Instead of loading the InterpreterTrampolineEntry address into LR directly, use an ADR instruction to place into LR the address of a piece of code that jumps to the InterpreterTrampolineEntry instead. This makes a difference because BR is also constrained by BTI, whereas RET isn't. An alternative would have been to `Call` instead of `Jump` to the target bytecode and avoid the ADR instruction altogether, but I wanted to keep the same behaviour with respect to the return stack that the existing code exhibits. Also add a comment to src/regexp/arm64/regexp-macro-assembler-arm64.cc for a similar use of LR that should eventually be removed.

Calls with a spread expression in a non-final position get transformed to calls to Reflect.apply. This transformation is currently done in the parser, which does not compose well with other features (e.g. direct eval checking, optional chaining).

When making inlining decisions in the JSInliningHeuristic, it's possible that a Node is not a candidate on the first visit, but becomes a candidate in later visits due to other node reductions. These later visits should also result in the inlining decision being made. Until now this was prevented by the visit aborting early since the Node was added to the seen_ list on the first (unsuccessful) visit. This CL changes the seen_ insertion to happen only once a positive inlining decision was made.

The test was extended in this CL: https://crrev.com/c/2762420 It now uses wasm::SimdShuffle, which is only available if webassembly is enabled. Thus, #if out the test if webassembly is disabled. Drive-by: Add a missing include.

This CL is part of a series that adds the C++ implementation of SwissNameDictionary, a deterministic property backing store based on Swiss Tables. This CL adds test-swiss-name-dictionary-infra.[h|cc], which contain the infrastructure for writing tests that simulatenously check the C++ and CSA/Torque implementation of SwissNameDictionary operations. The actual tests are added in a subsequent CL, which will be the last of this series.

We do not emit this opcode in the asm.js to wasm translator, hence we do not need to handle this case in the function body decoder. Replace it by a DCHECK to catch bugs where we might accidentally emit the opcode.

Port d16eefe0 Original Commit Message: We currently canonicalize shuffles in the architecture specific instruction selector. This has the drawback that if we want to pattern match on nodes that have a shuffle as input, they need to individually canonicalize the shuffle. There can also be a subtle bug if we canonicalize the same shuffle node twice (see bug for details). This moves the canonicalization to "construction time", in wasm-compiler, when building the graph. As such, any pattern matches in instruction-selector will only need to deal with canonicalized shuffles. We introduce a new kind of parameter for shuffle nodes, ShuffleParameter, to store the 16 bytes plus a bool indicating if this is a swizzle. A swizzle essentially: inputs to the shuffle are the same or all indices only touch 1 input. We calculate this when canonicalizing, so store this bit of information inside of the node's parameter. We update the tests in x64 to handle special cases where, even though the node's inputs are not swapped (due to canonicalization), they need to be swapped for the specific instruction selected (e.g. palignr). The test data also contains canonicalized shuffles, so we have to manually canonicalize them.
