This function should properly forward any exceptions it encounters, instead of silently swallowing them. Being an API function, that means moving them from "pending" to "scheduled" state.

Heap::ReportExternalMemoryPressure() uses a slightly different behavior for incremental marking steps than AdvanceFromTask() or AdvanceOnAllocation(). This CL switches this method to use AdvanceOnAllocation().

StringConstantXXX were introduced when we switched to concurrent compilation, as a way to build strings in Turbofan in a background thread, without having to actually allocate them on the main heap from the background. See https://crrev.com/c/1221807. Now that we have local heaps, we can actually allocate strings from the background, making StringConstantXXX useless. Moreover, we would fold constant string concatenations into ConsString, which sounds a bit dubious for performance. Now, small constant string concatenations will be folded into SeqStrings, while larger ones will remain ConsString, just to avoid the quadratic worst-case.

The CL https://crrev.com/c/3807594 changed the scope retrieval search to a DFS over the scope tree. This makes it no longer necessary to special case for the `DefaultBaseConstructor` scope so we can delete that code. A separate follow-up will prune the DFS slightly but not as much as we tried to initially.

This CL adds the shared barrier to the RecordWrite builtin which is used in generated code for builtins, interpreted and optimized code. The out-of-line part of the barrier now checks whether either the POINTERS_TO_HERE_ARE_INTERESTING or the IN_SHARED_HEAP bit is set in the value object's page flags. Outside of marking the RecordWrite builtin now needs to check whether to insert into the generational or shared remembered set. Inserting into the shared remembered set will always call into C++ code. During marking the RecordWrite builtin now also needs to check whether this store created an old-to-shared pointer.

ML-TF tiering remains very similar to Ignition-TF tiering: - When the interrupt budget is exhausted, enter the TieringManager which potentially decides to tier up and sets the appropriate TieringState on the FeedbackVector. - The prologue on ML function entry recognizes the TieringState (and also available cached TF code) and starts compilation and/or jumps into optimized code. TODOs: - ML-to-TF OSR is not yet supported. - ML code is no longer cached on the FeedbackVector. - Tracing is rudimentary. - The generated function-entry prologue is fairly large and must be either minimized or extracted into a builtin. - Tiering involving Sparkplug is not entirely robust yet (Sparkplug code may be installed with unexpected timing).

This adds a new {base::OS::SetDataReadOnly} method, which is similar to {SetPermissions(kRead)}, but using another system call on Windows such that it works on pages in the data segment. {VirtualAlloc} will fail if called on a page of the data section, whereas {VirtualProtect} succeeds. For the general {SetPermissions} API we still want to use {VirtualAlloc} though, as it also changes the "committed" state of the pages. Note that we do not add a platform API for this, as the memory was never allocated through the platform. We just directly protect it in V8.

This reverts https://crrev.com/c/3778717, and also switches "Promise" to a boolean enum. The underlying clang crash is fixed, see linked issue.
