[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

Reland "[wasm-gc] Remove abstract rtts" This is a reland of b77deeca4bd65b006a3a6c7344c2bbabd4514122 Changes compared to original: Add explicit narrowing casts in tests for MSVC. Original change's description: > [wasm-gc] Remove abstract rtts > > In the latest wasm-gc spec, rtts of abstract types are no longer > allowed. Consequently, canonical rtts of concrete types always have > a depth of 0. > > Changes: > - Change the immediate argument of rtts to a type index over a heap > type. Abstract it with TypeIndexImmediate in function body decoding. > This affects: > value_type.h, read_value_type(), decoding of relevant opcodes, > wasm subtyping, WasmInitExpr, consume_init_expr(), and > wasm-module-builder.cc. > - In function-body-decoder-impl.h, update rtt.canon to always produce > an rtt of depth 0. > - Pass a unit32_t type index over a HeapType to all rtt-related > utilities. > - Remove infrastructure for abstract-type rtts from the wasm compilers, > setup-heap-internal.cc, roots.h, and module-instantiate.cc. > - Remove ObjectReferenceKnowledge::rtt_is_i31. Remove related branches > from ref.test, ref.cast and br_on_cast implementations in the wasm > compilers. > - Remove unused 'parent' field from WasmTypeInfo. > - Make the parent argument optional in NewWasmTypeInfo, CreateStructMap, > and CreateArrayMap. > - Use more convenient arguments in IsHeapSubtypeOf. > - Update tests. > > Bug: v8:7748 > Change-Id: Ib45efe0741e6558c9b291fc8b4a75ae303146bdc > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2642248 > Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72321} Bug: v8:7748 Change-Id: I22b204b486fd185077cd6c7f15d492f5143f48fe Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2650207 Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#72355}
