This is the first step in unification of concurrent and main thread marking visitors. The new MarkingVisitorBase will become a base class for all marking visitors and will remove the existing code duplication. This is a refactoring without behavior change. Subsequent CL will change the main thread marking visitor to derive from the new base class.

The `capture_ix` refers to all captures while `capture_count` only refers to named captures. Clarified by renaming `capture_count` to `named_capture_count` and removing the incorrect part of the DCHECK. The `>= 1` part of the condition must still hold since named captures can only refer to explicit capture groups, which start at index 1.

There are a couple of bugs here: 1. The immediate used for vinsertps is wrong when lane == 1, the first two bits specify which element of the source is copied, and it should always be 00, 01 to copy the first 2 lanes of source. 2. For both cases, the second insertps call should be using dst as the src, since dst was already updated by the first insertps call, it was incorrectly using the old value of src. This was probably working correctly because in many cases dst and src happened to be the same register. 3. rep cannot be same as dst, because dst is overwritten, and rep should stay the same I also modified the F64x2ReplaceLane to test separately for replacing lane 0 and lane 1. Fixed bug 3. for arm and arm64. Bug: v8:9728 Change-Id: Iec6e48bcfbc7d27908dd86d5f113a8b5dedd499b Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1877055Reviewed-by:

When inlined allocations are disabled, the space->limit() does not point to the end of the current page. Instead, it points to the current allocation pointer so is the same as space->top(). See how the limit is computed, if heap()->inline_allocation_disabled(), then the limit will be the same as the requested allocation area: ``` Address SpaceWithLinearArea::ComputeLimit(Address start, Address end, size_t min_size) { DCHECK_GE(end - start, min_size); if (heap()->inline_allocation_disabled()) { // Fit the requested area exactly. return start + min_size; } else if (SupportsInlineAllocation() && AllocationObserversActive()) { // ... } else { // The entire node can be used as the linear allocation area. return end; } } ``` If we want to simulate filling up a whole page in the new space, we can instead look at the ToSpace's page_high() which will be the end of the current page in which we're allocating.

The {IsWasmFrame} check in {ComputeLocationFromStackTrace} only returned true for compiled frames, but not for interpreted ones. Thus, for interpreted frames we would run into the code for JS frames, which assumes that a {JSFunction} is available. This CL fixes this issue by renaming {IsWasmFrame} to {IsWasmCompiledFrame}, and introducing a new {IsWasmFrame} method which returns true for both compiled and interpreted frames.

This change begins making use of the fact that Torque now knows about the relationship between classes and instance types, to replace a few repetitive lists: - Instance type checkers (single and range), defined in src/objects/instance-type.h - Verification dispatch in src/diagnostics/objects-debug.cc - Printer dispatch in src/diagnostics/objects-printer.cc - Postmortem object type detection in tools/debug_helper/get-object-properties.cc Torque is updated to generate four macro lists for the instance types, representing all of the classes separated in two dimensions: classes that correspond to a single instance type versus those that have a range, and classes that are fully defined in Torque (with fields and methods inside '{}') versus those that are only declared. The latter distinction is useful because fully-defined classes are guaranteed to correspond to real C++ classes, whereas only-declared classes are not. A few other changes were required to make the lists above work: - Renamed IsFiller to IsFreeSpaceOrFiller to better reflect what it does and avoid conflicts with the new macro-generated IsFiller method. This is the part I'm most worried about: I think the new name is an improvement for clarity and consistency, but I could imagine someone typing IsFiller out of habit and introducing a bug. If we'd prefer to keep the name IsFiller, my other idea is to rename FreeSpace to VariableSizeFiller and Filler to FixedSizeFiller. - Made Tuple3 extend from Struct, not Tuple2, because IsTuple2 is expected to check for only TUPLE2_TYPE and not include TUPLE3_TYPE. - Normalized the dispatched behavior for BigIntBase and HeapNumber. - Added a few new object printers.
