This removes the usage of retaining_path_mode template parameter in main thread marking visitor and makes the incremental visitor identical to the stop-the-world visitor.

Before this change large fixed arrays were visited in chunks of 32KB on the main thread. Now large fixed arrays are divided into chunks of kMaxRegularHeapObjectSize, which is consistent with large fixed array processing on concurrent threads and make more sense considering that regular fixed arrays are visited in one go.

After fixing https://crbug.com/v8/8916, background compilation scales far beyond 10 threads, especially for TurboFan (where much more work is parallelizable). Thus, remove the limit of 10 background compilation tasks, and use all available threads instead.

Moves all of the KeyedSloppyArguments functions out of CodeStubAssembler and into builtins-handler-gen.cc which is the only place they're used. Bug: v8:9810 Change-Id: Ie52bdf24b7890943b89007f566dd18fe644a5996 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1895558Reviewed-by:

This re-enables verification for RO_SPACE when V8_SHARED_RO_HEAP is defined. This required refactoring PagedSpaceObjectIterator and methods in its calling chain to explicitly pass the PagedSpace and Heap pointers through as they cannot be obtained from the Page in this mode. Also removes unused Page::Print() method. Bug: v8:7464 Change-Id: Ibc2c147a7bde6723f43bbaf93cf1db93e76c611e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1893350Reviewed-by:
