This CL is a step towards reversing JS stack arguments for TurboFan. It does the following: 1. Add StackOrder to CallInterfaceDescriptor 2. Reverse arguments in TF backend for JS calls. 3. Cleanup TFJ builtins interface descriptors, since calls for these builtins already reverse the arguments, we don't need to reverse the interface descriptor anymore.

The Isolate is only used to access the wasm engine, and the accounting allocating. The latter is also linked directly from the wasm engine, and the engine is linked from the native module, to which the DebugInfoImpl already has access. Hence, this CL removes the redundant Isolate pointers, and just accesses the engine and the allocator via the NativeModule.

If multiple isolates share the same module, and the debugger gets enabled, then we trigger tier down in each isolate separately. To avoid generating too much code, we only recompile functions that are not already in the right tier. This CL is only the first step towards an actual fix. Since we only check already installed code (and ignore compilations that are already scheduled), we might still compile the same functions multiple times. A second CL will make sure that only one recompilation is running at the same time.

This CL introduces the SyncStreamingDecoder to support streaming compilation when --single-threaded is set. The SyncStreamingDecoder buffers all bytes it receives over {OnBytesReceived}, and compiles them synchronously upon {Finish}. In addition to introducing SyncStreamingDecoder, this CL does the following changes: * Redirect streaming compilation to the new streaming decoder if --no-wasm-async-compilation is set. This flag is set if --single-threaded is set. * Extend the test-streaming-compilation.cc tests to test also the new streaming decoder.

We can't consistently rewire the successor blocks of an unreachable node to disconnect them from the graph when we are trying to maintain the schedule. Instead simply leave the code there. As a future optimization we could add a proper scheduled dead code elimination phase which can deal with this. As a side-effect, one of the tests sees a int64 DeadValue, so add support for that in the instruction selector.

Sometimes CSA code carefully constructs a mask to check several bitfields at once. Thus far, such a check has been very awkward to write in Torque. This change adds a way to do so, using the non-short-circuiting binary `&` operator. So now you can write an expression that depends on several bitfields from a bitfield struct, like `x.a == 5 & x.b & !x.c & x.d == 2` (assuming b is a one-bit value), and it will be reduced to a single mask and equality check. To demonstrate a usage of this new reduction, this change ports the trivial macro IsSimpleObjectMap to Torque. I manually verified that the generated code for the builtin SetDataProperties, which uses that macro, is unchanged.

The proposal uses the lane shape, e.g. i64x2.anytrue, and we were using s1x2.anytrue in our opcodes. This was a legacy naming, because we were trying to bitpack the booleans. Now that we aren't doing that, rename these to be more consistent with the proposal. This was done with a straightforward sed script, changing both cpp code and also some comments in mjsunit test files.

Currently, if d8 is run with the --turbo-profiling flag, it prints info about every TurboFan-compiled function. This info includes the number of times that each basic block in the function was run. It also includes text representations of the function's schedule and code, so that the person reading the output can associate counters with blocks of code. The data about each function is currently stored in a BasicBlockProfiler::Data instance, which is attached to a list owned by the singleton BasicBlockProfiler. Each Data contains an std::vector<uint32_t> which represents how many times each block in the function has executed. The generated code for each block uses a raw pointer into the storage of that vector to implement incrementing the counter. With this change, if you compile with v8_enable_builtins_profiling and then run with --turbo-profiling, d8 will print that same info about builtins too. In order to generate code that can survive being serialized to a snapshot and reloaded, this change uses counters in the JS heap instead of a std::vector outside the JS heap. The steps for instrumentation are as follows: 1. Between scheduling and instruction selection, add code to increment the counter for each block. The counters array doesn't yet exist at this point, and allocation is disallowed, so at this point the code refers to a special marker value. 2. During finalization of the code, allocate a BasicBlockProfilingData object on the JS heap containing data equivalent to what is stored in BasicBlockProfiler::Data. This includes a ByteArray that is big enough to store the counters for each block. 3. Patch the reference in the BuiltinsConstantsTableBuilder so that instead of referring to the marker object, it now refers to this ByteArray. Also add the BasicBlockProfilingData object to a list that is attached to the heap roots so it can be easily accessed for printing. Because these steps include modifying the BuiltinsConstantsTableBuilder, this procedure is only applicable to builtins. Runtime-generated code still uses raw pointers into std::vector instances. In order to keep divergence between these code paths to a minimum, most work is done referring to instances of BasicBlockProfiler::Data (the C++ class), and functions are provided to copy back and forth between that type and BasicBlockProfilingData (the JS heap object). This change is intended only to make --turbo-profiling work consistently on more kinds of functions, but with some further work, this data could form the basis for: - code coverage info for fuzzers, and/or - hot-path info for profile-guided optimization.
