Currently the initial old generation size is set to the half of the maximum old generation size. This is problematic for huge heaps. This patch introduces an upper bound of 512MB (256MB) for x64 (x32).

We used to set disable optimization bits in SFI to NeverOptimize in lite mode to avoid optimizing in tests. Now, tests that need optimization use intrinsics to force feedback vector allocation. Hence this is no longer necessary. Bug: v8:8394 Change-Id: I0aeaeacc34d838cf15698a9227b6964292b97240 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1611545Reviewed-by:

Previously we had to use CheckHeapObject in front of every CheckMaps, CompareMaps and TransitionElementsKind operation. Now these operators request HeapObject representation themselves (requiring for CompareMaps and TransitionElementsKind to remove the kNoDeopt property). This means we only do CheckHeapObject for StoreField to a field that has HeapObject representation. This not only leads to smaller graphs in the compiler, but also removes most uses of the CheckHeapObject operator, which doesn't express a real semantic property in the compiler frontend.

We use the predicate NeedsCheckHeapObject in the compiler frontend to determine whether we can skip introducing CheckHeapObject nodes. But this predicate would also walk up the graph in case of Phis, which can result in really long compilation times (on the main thread). In the report in https://github.com/nodejs/node/issues/27667, the compiler frontend alone took around 4-5mins of main thread time for a single function. With this patch the time goes down to 4-5ms.

This annotation indicates that the class itself is not instantiated, and does not have its own instance type: The instance types that logically belong to the class are the instance types of the derived classes. Currently, we need the indication @dirtyInstantiatedAbstractClass for several classes that are used as both, abstract base classes and concrete classes. The prime example is JSObject which is the base for many other classes, and also serves as the class to allocate plain JSObjects. The annotation is purposefully ugly because in the future we should refactor code to make it unnecessary. Another annotation we introduce is @hasSameInstanceTypeAsParent, which indicates another design pattern that currently occurs in the code-base: Some Torque classes have the same instance types as their parent class, but rename some fields, or possibly have a different map. In such cases, the parent class is not abstract and the derived classes can be seen as refinements of this class (that, for example, narrows the type of a field). In the future, Torque should accomodate this pattern better, but at moment we are content with just indicating where it is used.

Previously we had a special, unshared map on the native context that was used for results of builtin iterators, which was different from the map that is created from an object literal like `{value, done}`. This not only leads to unnecessary polymorphism, but also makes it impossible for user defined iterators to take the fast-paths that we have in various places (i.e. in collections or promises). With this change we now properly share the map for `{value, done}` and use that for the builtin iterator result objects, as well as the fast-paths. Drive-by-fix: Remove the restrictions on map caching and transition caching during bootstrapping. This no longer makes sense.

This CL adds support for macros, builtins, generics and specializations for the "textDocument/symbol" request. To filter out implicitly created specializations, the "is_user_defined" flag is hoisted from Macro to the Declarable super class. As a side-effect, errors thrown during specialization now have the correct SourcePosition. Drive-by-change: Using "Goto Definition" on the identifier of the specialization will jump to the associated generic.

When using the fast-properties optimization for `delete` with constant fields we don't properly invalidate the constness on the original map and might thereby just follow the same transition again later with the same object, effectively violating the constness of that field. This disables the fast-properties optimization for `delete` in case of a field marked as "const" as a quick-fix. We might still want to change the logic to properly invalidate the "const" bit later.
