This CL adds a "random state" to the Smi Root list and implements a basic Linear congruential pseudo random number generator in Torque. The RNG is used to determine the pivot element for sorting. This will prevent the worst cases for certain data layouts. Drive-by-fix: Make sorting of ranges and execution pauses for profviz deterministic by adding a secondary sorting criteria.

SharedFunctionInfos store their original function literal's id. This is also their index in the Script's SFI list. Since the function literal id is only needed for lazy compilation and live edit, we can calculate it on-the-fly by linear search in the Script SFI list, and save a field on the SFI. If this regresses compile performance, we could alternatively store the function literal id on the preparsed scope data as future work.

This CL changes the behaviour of number literals. Large integer literals (bigger than Smi, but fit into int32) should have type "constexpr int32" instead of "constexpr float64".

This CL introduces a new gn argument: v8_enable_pointer_compression which is false by default. All the changes done in this CL are made under this flag.

Add an inspection callback for embedders that allows tracking of `Atomics.wait()` calls in order to enable diagnostic tooling around it, as well as providing a way to break out of an `Atomics.wait()` call without having to fully terminate execution. The motivation here is that this allows embedders to perform somewhat customizable deadlock detection.

This removes the obsolete support to create {WASM_COMPILED} stack frames within the out-of-line trap handler code. All trapping code needs to push such a frame on entry by now, because the instance object is pushed implicitly as part of the prologue. Deferred frame building would not have access to a valid instance object.

Port c96ac82c Original Commit Message: This makes stack checks in WasmCode independent of the underlying Isolate by loading the limit address from the WasmInstanceObject instead of embedding it into the instruction stream. It hence removes the last use of the Isolate field from WasmGraphBuilder. Additionally this introduces the notion of a "runtime stub" which represents stub code global to the NativeModule that can be directly called from each WasmCode in the same module. These stubs can act as trampolines via which Isolate-independent WasmCode can enter other V8 builtins or runtime functions that remain Isolate-dependent. They will eventually replace the current "trampoline" in a NativeModule.

This implements a reasonable overload resolution strategy for operators: An overload is selected if it is strictly better than all alternatives. This means that it has to be strictly better in at least one parameter, and better or equally good in all others. When comparing a pair of corresponding parameters of two overloads... ... they are considered equally good if: - They are equal. - Both require some implicit conversion. ... one is considered better if: - It is a strict subtype of the other. - It doesn't require an implicit conversion, while the other does. If no overload is strictly better than all alternatives, this results in a compile error.
