To fix 6 gn check errors, this adds a cppgc_headers dep to v8_headers. To resolve the resulting cycle, it also changes v8_libplatform to depend on v8_config_headers since it only needs v8config.h.

Be explicit about source positions for `Return`s in the BytecodeGenerator, and only do self-healing explicitly in the `ReturnStatement` translation, where an end position of `kNoSourcePosition` is turned into the return position of the function literal. This allows us to reason more easily about which `Return`s actually receive a meaningful source position, and in particular it allows us to construct the internal `Return`s for `yield` and `yield*` with no source position attached to them. Previously they'd get the source position for the implicit (final) return attached to it, which confused the debugger and led to breakpoints being set in the completely wrong spot. Considering the simplified example ``` function* foo(){ var a = 1; } ``` this would previously generate the following bytecode ``` 0 : SwitchOnGeneratorState r0, [0], [1] { 0: @20 } 4 : Mov <closure>, r2 7 : Mov <this>, r3 13 E> 10 : InvokeIntrinsic [_CreateJSGeneratorObject], r2-r3 14 : Star0 13 E> 15 : SuspendGenerator r0, r0-r1, [0] 20 : ResumeGenerator r0, r0-r1 24 : Star2 25 : InvokeIntrinsic [_GeneratorGetResumeMode], r0-r0 29 : SwitchOnSmiNoFeedback [1], [2], [0] { 0: @39, 1: @36 } 33 : Ldar r2 13 E> 35 : Throw 36 : Ldar r2 30 S> 38 : Return <=========================== internal Return 27 S> 39 : LdaSmi [1] 41 : Star1 42 : LdaUndefined 30 S> 43 : Return ``` where everything between offset 4 and 42 corresponds to the implicit yield at the beginning of every generator function, in particular the code between 20 and 42 corresponds to that initial yields resumption logic. Notice how the internal Return at offset 38 gets assigned the source position of the function literal (the same as the implicit return at the end). This confuses the debugger quite a bit when trying to set a breakpoint on the closing brace, since it's going in bytecode order and will thus discover the `Return` at offset 38 first (matching the source position 30 it's currently looking for) and setting the breakpoint there. This `Return` bytecode however is only executed when the generator is resumed via `GeneratorPrototype.return()`, and it'll not hit when the developer uses the generator normally, which is not the desired behavior and extremely confusing (especially since stepping on the other hand works as expected). With this patch, we no longer slap a source position (and in particular not the function literal's return position) onto these internal `Return`s as you can see from the generated bytecode below: ``` 0 : SwitchOnGeneratorState r0, [0], [1] { 0: @20 } 4 : Mov <closure>, r2 7 : Mov <this>, r3 13 E> 10 : InvokeIntrinsic [_CreateJSGeneratorObject], r2-r3 14 : Star0 13 E> 15 : SuspendGenerator r0, r0-r1, [0] 20 : ResumeGenerator r0, r0-r1 24 : Star2 25 : InvokeIntrinsic [_GeneratorGetResumeMode], r0-r0 29 : SwitchOnSmiNoFeedback [1], [2], [0] { 0: @39, 1: @36 } 33 : Ldar r2 13 E> 35 : Throw 36 : Ldar r2 38 : Return 27 S> 39 : LdaSmi [1] 41 : Star1 42 : LdaUndefined 30 S> 43 : Return ``` This also allows us to remove the break position finding hack that was kept in BreakIterator::BreakIndexFromPosition() for generators and modules.

The main problem here is that the macro-assembler for Pmaddubsw and Pmaddwd expects dst == src1 when AVX is not supported. For Pmaddwd, we use an existing macro to define the function. For Pmaddubsw, we do the AVX check inline and use movaps if not supported because it requires a SSSE3 scope, and we don't have an existing macro to do this (we can find other uses and clean up as necessary in the future).

v8_libsampler was previously split off to serve goals that were never achieved and seem unlikely to be. Since the division creates a dependency cycle between v8_base_without_compiler and v8_libsampler (where one edge is a #include that breaks gn check), this moves sampler.* back into v8_base_without_compiler and removes the v8_libsampler target.

Split out all the headers from v8_compiler/v8_compiler_opt and v8_base_without_compiler into v8_internal_headers since the headers have inter-dependencies that otherwise make it impossible to satisfy gn check. Also adds new v8_header_set torque_runtime_support that exports src/torque/runtime-support.h separately from the generated headers. This reduces the number of gn check failures from 169 to 59.

We got a TSAN warning because of the non-atomic store of the code pointer in a JSFunction in the interpreter builtin (when the pointer is discovered in the FeedbackVector). However, we know this store is safe because we guarantee a release store into the FeedbackVector. However, TSAN can't recognize this interesting triple relation. Therefore, we mark the fields we need to read from TurboFan as relaxed.

For adding stack checks in optimized code, we compute a conservative estimate of the frame size in the case of a deoptimization. Earlier we included the size of arguments adaptor frames used when actual arguments didn't match formal parameter count. Though we don't have an explicit adaptor frame, we should still include the size of these additional arguments when computing the frame size.

Calls >4gb may have pretty bad performance on 64bit processors that use 32bits to encode branch prediction. By passing in a function in the binary as a hint to mmap it's more likely we'll be given an address close to the binary. This may significantly improve performance on many types of 64bit cores, especially those without hyperthreading.

To improve performance of parking, keep the thread state in an atomic variable instead of protecting it with a mutex. However the mutex was used e.g. to force Unpark() to block while the safepoint operation was still running. Therefore the safepoint algorithm has to change as well. Park() and Unpark() use CAS operation to transition the state. Safepoint() uses a relaxed load for checking whether a safepoint was requested. Since Safepoint(), Park() and Unpark() all have a slow path, there is no need for busy-waiting on the main thread. We need two more ThreadStates: * SafepointRequested: This state is set by GlobalSafepoint to force Running threads into the slow path on Safepoint() and Park(). This state also replaces the separate atomic<bool> safepoint_requested_ field we used before. * ParkedSafepoint: This state is set by GlobalSafepoint as well to force parked threads into the slow path on Unpark(). When stopping all threads, GlobalSafepoint transitions states from Running --> SafepointRequested and Parked --> ParkedSafepoint to force the slow path for all three methods. After performing the transition for each thread we know the exact number of Running threads and wait until each of them either reached a safepoint or parked itself.
