Michael Lippautz authored
Unified heap support in V8 requires having another (at least internal) heap that implements a unfied garbage collection strategy. This will not re-use the already existing cppgc::Heap because there should be no way in creating such a heap externally or scheduling stand-alone garbage collections. In order to have a common token, this CL introduces AllocationHandle which can be passed to MakeGarbageCollected to allocate C++ objects. V8 (soon) and the stand-alone heap both have methods to retrieve such a handle. This works around a problem with creating diamond class hierarchies when a base class would be exposed on the public API level. Fast paths for Blink are still possible because allocation handles can be cached the same way (e.g. global, or TLS) as a heap can be cached.

Foozie came up with a mind-boggling example hitting a similarly mind-boggling bug: object construction (JSObject::New) wants to create the constructor's function initial map (JSFunction::GetDerivedMap -> JSFunction::EnsureHasInitialMap). To do so, it calls JSFunction::CalculateExpectedNofProperties. This harmless sounding function triggers compilation of the function. Since we're running with --always-opt, this is an optimizing compilation. Turbofan ends up depending on the function's "prototype" property, for which it wants to create the initial map so that it can install the code dependency. That is, EnsureHasInitialMap is reentered. At this point there is no further compilation attempt because the bytecode now exists. The initial map is created and installed on the function, and TF records the code dependency on that map. When CalculateExpectedNofProperties returns control to the outer EnsureHasInitialMap, yet another initial map is created and set on the function, forgetting the previous one and thus the code dependency. I'm not sure if this bug can only be observed with --always-opt. The fix is general.

{PopToRegister} will most likely find that the stack slot is already holding a register (89% of cases on epic). Thus put the fast path for this in the header, so it can be inlined. Also, {GetUnusedRegister} will mostly find an unused register (95% on epic). Hence, make sure that the code for spilling a register is not inlined.
