[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.

Plumb import assertions through SourceTextModuleDescriptor's ModuleRequestMap This change plumbs import assertions from SourceTextModuleDescriptor's ModuleRequestMap into SourceTextModuleInfo via a new ModuleRequest type, where previously there had been only the specifier. SourceTextModuleDescriptor::module_map now deduplicates module requests using the specifier and the import assertions. Continuing to use the specifier alone would cause a loss of information in the event that a module imports from the same specifier multiple times using different sets of assertions. Failing to deduplicate at all would result in multiple requests for statements like `import {a,b,c} from "foo.js"`, which would be a potential performance issue. See design doc at https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY for more detail on this decision. v8::internal::ModuleRequest holds the assertions as an array of the form [key1, value1, position1, key2, value2, assertion2, ...]. However the parser still needs to use a map, since duplicate assertion keys need to be detected at parse time. A follow-up change will ensure that assertions are sorted using a proper lexicographic sort.

[torque] Begin porting ScopeInfo to Torque This change adds Torque field definitions for ScopeInfo and begins to use the Torque-generated accessors in some places. It does not change the in-memory layout of ScopeInfo. Torque compiler changes: - Fix an issue where the parser created constexpr types for classes based on the class name rather than the `generates` clause. This meant that generated accessors referred to the imaginary type HashTable rather than the real C++ type FixedArray. - Don't pass Isolate* through the generated runtime functions that implement Torque macros. Maybe we'll need it eventually, but we don't right now and it complicates a lot of things. - Don't emit `kSomeFieldOffset` if some_field has an unknown offset. Instead, emit a member function `SomeFieldOffset()` which fetches the slice for some_field and returns its offset. - Emit an `AllocatedSize()` member function for classes which have complex length expressions. It fetches the slice for the last field and performs the multiply&add to compute the total object size. - Emit field accessors for fields with complex length expressions, using the new offset functions. - Fix a few minor bugs where Torque can write uncompilable code. With this change, most code still treats ScopeInfo like a FixedArray, so I would like to follow up with some additional changes: 1. Generate a GC visitor for ScopeInfo and use it 2. Generate accessors for struct-typed fields (indexed or otherwise), and use them 3. Get rid of the FixedArray-style get and set accessors; use TaggedField::load and similar instead 4. Inherit from HeapObject rather than FixedArrayBase to remove the unnecessary `length` field After that, there will only be one ugly part left: initialization. I think it's possible to generate a factory function that takes a bunch of iterator parameters and returns a fully-formed, verifiably correct ScopeInfo instance, but doing so is more complicated than the four mostly-mechanical changes listed above.
