Adds allocation-based heap growing strategy that triggers GC based on some limit. The limit is computed based on previous live memory and a constant growing factor. For invoking GC, we support two modes: with and without conservative stack scanning. Without conservative stack scanning, an invoker makes sure that we schedule a GC without stack using the existing platform.

If multiple workers are sharing the same module, the DevTools frontend will set the same breakpoints in all of them, but one after another. This CL tries to avoid repeated recompilation of that function in most cases. Only if we need special source positions for stack rewriting, we need to compile a special version.

When the last debugger is disabled, we tier up the module to TurboFan. Doing this in the background creates problems with profiling, where the debugger is disabled before starting to profile, in order to guarantee profiling of top-tier code. Hence this CL changes the logic such that we only return from the {TierUpAllModulesPerIsolate} methods once tier up is complete. Since the DevTools frontend disables all debuggers before starting a profile, this will ensure that all new calls execute TurboFan code. Because of this change, the {TriggerRecompilation} method is renamed to {RecompileForTiering}. The test cases stay unchanged (do a busy wait until tier up is done), because in the multi-isolates tests it is not guaranteed that tier up is complete after disabling a single debugger.

Reason for revert: Break CFI tests in chromium https://ci.chromium.org/p/chromium/builders/ci/Linux%20CFI/17438 Original change's description: > [heap] Make ReadOnlySpace use bump pointer allocation > > This changes ReadOnlySpace to no longer be a PagedSpace but instead it > is now a BaseSpace. BasicSpace is a new base class that Space inherits > from and which has no allocation methods and does not dictate how the > pages should be held. > > ReadOnlySpace unlike Space holds its pages as a > std::vector<ReadOnlyPage>, where ReadOnlyPage directly subclasses > BasicMemoryChunk, meaning they do not have prev_ and next_ pointers and > cannot be held in a heap::List. This is desirable since with pointer > compression we would like to remap these pages to different memory > addresses which would be impossible with a heap::List. > > Since ReadOnlySpace no longer uses most of the code from the other > Spaces it makes sense to simplify its memory allocation to use a simple > bump pointer and always allocate a new page whenever an allocation > exceeds the remaining space on the final page. > > Change-Id: Iee6d9f96cfb174b4026ee671ee4f897909b38418 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2209060 > Commit-Queue: Dan Elphick <delphick@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Cr-Commit-Position: refs/heads/master@{#68137} TBR=ulan@chromium.org,delphick@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago.

- Use a shorter code sequence for the most likely case (no NaNs or signed 0 errors), and use out-of-line code to handle those cases. - For the likely execution paths, F32x4Min goes from 8 to 6 instructions, while F32x4Max goes from 9 to 6 instructions. - Code size increases by 2 and 3 instructions (the test and branch, and for max, an extra move.
