... - a code range size agnostic version of InterpreterEntryTrampoline builtin. The new builtin is fully compatible with the default version and used as a template for creating interpreter entry trampoline Code objects when --interpreted-frames-native-stack is enabled. This CL introduces a new assembler option "position_independent_code" which affects the way builtin calls are generated. This mode is enabled only for InterpreterEntryTrampolineForProfiling. Motivation: * InterpreterEntryTrampoline uses RelocInfo::CODE_TARGET for calling other builtins which requires the code range to be small enough to allow PC-relative jumps/calls between Code objects. This is the reason why --interpreted-frames-native-stack was not supported on arm and might not work on arm64 because the code range is bigger than the max PC-relative distance for call/jump instructions. The new builtin calls other builtins via builtins entry table which makes the code fully relocatable and usable for any code range size. * RelocInfo::CODE_TARGET requires a target code to be materialized as a Code object which contradicts the Code-less builtins goal. * The --interpreted-frames-native-stack is rarely used in the wild but we have to pay the price of deserializing InterpreterEntryTrampoline builtin as a Code object which consumes address space in the code range and thus limits the number of V8 isolates that can be created because of code range exhaustion. Now the pointer compression cage becomes the limiting factor instead of the code range. * We can remove complicated logic of Factory::CopyCode() and respective support on GC side.

The wasm instance got pushed three times in the lazy-compile builtin: 1) as part of the parameters; 2) as a parameter for the runtime function; 3) to load the jump table address after the runtime function; The third push can be avoided by loading the jump table address after all parameters get loaded from the stack again.

Since this didn't regress performance as expected, we can now remove those versions of the builtin.

Port 22a16bda Original Commit Message: The Runtime_WasmCompileLazy function was returning a ptr-sized address, wrapped in an Object. This worked because no GC is triggered between the return from the runtime function and the point where we jump to the returned address. In a pointer-compressed world though, generated code assumes that all objects live in the same 4GB heap, so comparisons only compare the lower 32 bit. On a 64-bit system, this can lead to collisions where a comparison determines that the returned address equals a heap object, even though the upper 32-bit differ. This happens occasionally in the wild, where the returned function entry pointer has the same lower half than the exception sentinel value. This leads to triggering stack unwinding (by the CEntry stub), which then fails (with a CHECK) because there is no pending exception. This CL fixes that by returning a Smi instead which is the offset in the jump table where the kWasmCompileLazy builtin should jump to. The builtin then gets the jump table start address from the instance object, adds the offset that the runtime function returned, and performs the jump. We do not include a regression test because this failure is very spurious and hard to reproduce.

Doc: https://bit.ly/revive-restart-frame Context: https://crrev.com/c/3582395 (jumbo CL with the whole feature) This CL adds a new builtin called "RestartFrameTrampoline". This trampoline is relatively simple: It leaves the current frame and re-invokes the function. This essentially restarts the function and is one of the key components required to bring back the "Restart frame" DevTools debugging feature. The builtin is closely related to the "FrameDropperTrampoline" removed in the CL https://crrev.com/c/2854750. The key difference is that the "FrameDropperTrampoline" dropped to an "arbitrary" frame pointer before restarting the function (arbitrary in the sense that it was provided as an argument). This caused issues as the feature was implemented in a way that the frame pointer wasn't necessarily valid anymore. In comparison, the "RestartFrameTrampoline" relies on the V8 unwinder to drop it in the correct frame first and is then invoked via either the CEntry stub or the deoptimizer (see design doc for details).

- Restructure the runtime function implementation. - Rename osr_loop_nesting_level to osr_urgency and add helpers. The motivation for the latter: I've always struggled with the `osr_loop_nesting_level` term; it neither matches terminology of what it's compared against (= the loop depth), nor implies what it's used for (= osr is triggered when `loop depth < osr nesting level`). In this CL it's renamed to `osr_urgency` to reflect that as urgency rises, we consider more and more loops as OSR candidates.

Port 8a0d1b6f Original Commit Message: Modernise the RegList interface to be a proper class, rather than a typedef to an integer, and add proper methods onto it rather than ad-hoc bit manipulation. In particular, this makes RegList typesafe, adding a DoubleRegList for DoubleRegisters. The Arm64 CPURegList isn't updated to use (or extend) the new RegList interface, because of its weird type-erasing semantics (it can store Registers and VRegisters). Maybe in the future we'll want to get rid of CPURegList entirely and use RegList/DoubleRegList directly.

The functionality is unused and we are simplifying OptimizationMarker usage. Drive-by: Remove unused return value of Compiler::CompileOptimized. Drive-by: Don't add kStackSpaceRequiredForCompilation as gap to the stack check when compiling concurrently, i.e. on another thread.

Create and return the chained promise, which resumes the suspended wasm continuation once the JS promise resolves: - Add stub for the WasmResume builtin, which will resume the given suspender. - Add the JS function wrapper for the builtin. - On suspension, return promise.then(onFulfilled) to the prompt.
