74ede07103 Fix PerformCastCheck on v8::Data (again)
See crrev.com/c/2383030

PerformCheckCast<Data>() itself should not invoke Data::Cast(), since
there is no such method and every publicly available value can be
casted to it anyway. This is an issue in e.g.
GetDataFromSnapshotOnce<Data>().

9d413c635d [api] Deprecate misleading v8::String::IsExernal method
v8::String::IsExternal is confusing since it only checks for external
two byte strings. The goal is to reintroduce String::IsExternal which
checks for one and two byte external strings after removing the old,
misleading api method.

- Add String::IsExternalTwoByte
- Deprecate String::IsExternal for now since it is misleading

c51041f454 [nci] Replace CompilationTarget with a new Code::Kind value
With the new Turbofan variants (NCI and Turboprop), we need a way to
distinguish between them both during and after compilation. We
initially introduced CompilationTarget to track the variant during
compilation, but decided to reuse the code kind as the canonical spot to
store this information instead.

Why? Because it is an established mechanism, already available in most
of the necessary spots (inside the pipeline, on Code objects, in
profiling traces).

This CL removes CompilationTarget and adds a new
NATIVE_CONTEXT_INDEPENDENT kind, plus helper functions to determine
various things about a given code kind (e.g.: does this code kind
deopt?).

As a (very large) drive-by, refactor both Code::Kind and
AbstractCode::Kind into a new CodeKind enum class.

e7e10aa70c [snapshot] Sanitize isolate during serialization
The isolate snapshot must not contain context-dependent objects, thus
root visitation must not reach context-dependent objects. This CL
sanitizes the isolate around serialization by clearing & later
restoring two lists: 1. feedback vectors for profiling tools, 2.
detached contexts.

Drive-by: Set an array buffer allocator for
SerializeDeserializeAndVerify.
Drive-by: Allow serialization of *another* native context when
serializing a native context.

93cfa4587b [heap] Add SharedReadOnlySpace for shared RO_SPACE
When RO_SPACE is to be shared, this constructs SharedReadOnlySpace
object (via ReadOnlySpace::DetachPagesAndAddToArtifacts) that contains
the shared artifacts and the original ReadOnlySpace is destroyed. This
is mostly a conceptual change and SharedReadOnlySpace behaves
identically to ReadOnlySpace (and subclasses it).

Also adds ReadOnlyArtifacts that contains the shared artifacts and which
is stored as a std::weak_ptr in a global so it can be destroyed when all
std::shared_ptrs to it are destroyed. Since this allows the ReadOnlyHeap
to be reconstructed when all Isolates are destroyed,
ReadOnlyHeap::ClearSharedHeapForTest is removed along with all uses
since that is now done automatically.

The ReadOnlyArtifacts class now owns all the shared artifacts and is
responsible for deleting them on exit (mostly via unique_ptr).

e04eb281a3 [base] Fix {StaticCharVector} and add {StaticOneByteVector}
{StaticCharVector}, according to its name, should return a
{Vector<const char>}. For getting a {Vector<const uint8_t>}, the method
should be called {StaticOneByteVector}, analog to the
{OneByteVector} methods that already exist.

Also, {StaticCharVector} is constexpr, but {StaticOneByteVector} cannot
be, since it contains a {reinterpret_cast}. The same holds for
{Vector::cast} in general.

This CL
- changes the return type of {StaticCharVector} to be
  {Vector<const char>},
- introduces a new {StaticOneByteVector} which returns
  {Vector<const uint8_t>},
- fixes constexpr annotations at various methods returning {Vector}s,
- refactors users of {StaticCharVector} to either use
  {StaticOneByteVector} instead, or work on {char} if that makes more
  sense.

9d3cca1cd3 s390: [arm] Add missing RELATIVE_CODE_TARGET iteration
Port b766299d2c
Port 9592b043ee
Port d915b8d668

Original Commit Message:

    Code object iteration was missing logic for RELATIVE_CODE_TARGET
    reloc entries. Garbage collection could thus miss objects that were
    referenced only as targets of pc-relative calls or jumps.

    RELATIVE_CODE_TARGETs are only used on arm, mips, and s390 and only
    at mksnapshot-time.

    This exposed another issue in that the interpreter entry trampoline
    copy we generate for profiling *did* contain relative calls in
    runtime-accessible code. This is a problem, since code space on arm is,
    by default, too large to be fully addressable through pc-relative
    calls. This CL thus also disables the related
    FLAG_interpreted_frames_native_stack feature on arm.

    objects.

858e3c7ef7 Compressing SnapshotData with zlib
This CL introduces, and turns on by default, compression for snapshots.
The compression is handled in SnapshotCompression, which is a new static
helper class for producing/consuming compressed SnapshotData.

To turn off snapshot compression (accomplished by removing calls of
Compress/Decompress) set the GN arg:
v8_disable_snapshot_compression = true

dec6dc4baf Prevent stack frame cache usage during isolate serialization
Individual frames of a stack frame in the frame cache might point
to the JSFunction of that corresponding stack frame. It is illegal to
serialize JSFunction objects in the isolate snapshot, so the attempt
to serialize the stack frame cache results in a crash. This can happen
when a warmup script is run, before a snapshot is created.

This CL fixes the crash by not utilizing the stack frame cache in case
the serializer is enabled.

c4f502ed4d Remove JS natives support, step 3
The natives blob was deprecated in V8 7.8. This CL removes all related
functionality, including:

- Build system support, i.e.: generation of natives_blob.bin and the
v8_extra_library_files gn flag.
- Related scripts (js2c.py, concatenate-files.py).
- Related API functions (SetNativesDataBlob,
InitializeExternalStartupData).
- Natives bootstrapping logic.
- The InternalArray type (previously exposed through natives).
- Other natives-exposed builtins.
- Inlining of these builtins.
- The dedicated 'uncached external one byte string' type.

Step 1 landed in https://crrev.com/c/1824944.
Step 2 landed in https://crrev.com/c/1835536.
Step 3 (this CL) removes these all functionality related to natives
support in V8.

As the next step in supporting huge typed arrays in V8, this moves the
external/data pointer from the FixedTypedArrayBase backing store to the
JSTypedArray instance itself, and replaces the special backing stores
with a plain ByteArray (removing all the code for the FixedTypedArrayBase
class hierarchy). By doing so, we can drastically simplify the system

Note: Several places in the code base used to check the instance type
of the elements backing store of a JSTypedArray instead of checking the
elements kind on the JSTypedArray map directly. Those had to be fixed,
since the backing store is now always a ByteArray.

Drive-by-fix: Move all the typed elements access related code into the

a335f2aeed [cleanup] Replace simple typedefs by using
This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.

This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
     perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'

Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.

9aa8b51704 [runtime] Remove explicit OneByte/TwoByte from InternalizeString
The type of the argument makes it clear what we're internalizing, and this
allows us to choose either one based on a template parameter.

878ccb33bd [cleanup] Avoid {Object::operator->}
This CL was generated by an automatic clang AST rewriter using this
matcher expression:

  callExpr(
    callee(
      cxxMethodDecl(
        hasName("operator->"),
        ofClass(isSameOrDerivedFrom("v8::internal::Object"))
      )
    ),
    argumentCountIs(1)
  )

The "->" at the expression location was then rewritten to ".".
