Make --stress-background-compile a V8 flag rather than a d8 flag, so
that it also tests unittests/cctests.
Now, with this flag, every top-level script compile (that fulfills a
couple of restrictions) will be both main-thread and background-thread
compiled, taking the result of the background compile. In the future,
we'll probably want to verify that the two results are equivalent.
One of the necessary changes to allow tests to pass was to introduce a
concept of a "temporary" script (with a temporary script id), which
doesn't get added to the script list. This is to avoid the main-thread
compile part of the stress-test having a debugger-visible side-effect,
e.g. in tests that enumerate scripts. We can't just create new ids for
such scripts, as then script-id expectation files no longer match.

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

String::NewFromLiteral is a templated function that takes a char[N]
argument that can be used as an alternative to String::NewFromUtf8 and
returns a Local<String> rather than a MaybeLocal<String> reducing the
number of ToLocalChecked() or other checks.
Since the string length is known at compile time, it can statically
assert that the length is less than String::kMaxLength, which means that
it can never fail at runtime.
This also converts all found uses of NewFromUtf8 taking a string literal
or a variable initialized from a string literal to use the new API. In
some cases the types of stored string literals are changed from const
char* to const char[] to ensure the size is retained.
This API does introduce a small difference compared to NewFromUtf8. For
a case like "abc\0def", NewFromUtf8 (using length -1 to infer length)
would treat this as a 3 character string, whereas the new API will treat
it as a 7 character string.
As a drive-by fix, this also fixes all redundant uses of
v8::NewStringType::kNormal when passed to any of the String::New*
functions.

Just a cleanup, should not change behavior, although we will allocate
more handles in some cases.
Also re-orders some of the implementations of the interface to try
and keep things consistent.
Included cleanup: Change CodeEventDispatcher so that it now implements
CodeEventListener, given that it had that exact interface already.
Also remove the macro dispatch to try and make things a bit easier to
read.

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.

Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.
Patchset 1 was auto-generated by using this clang AST matcher:
callExpr(
callee(
cxxMethodDecl(
hasName("start"),
ofClass(hasName("v8::internal::Vector")))
),
argumentCountIs(0))
Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

Most test-log tests create their own isolates, so initializing the cctest

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.
Drive-by: Ensure the builtins constants table does not contain Code
objects.

- Use unique ptrs for owned objects
- Remove friendship with CpuProfiler and replace with public API
- Remove unused method LogFailure()
- Remove StopProfiler() which was only used by LogFailure() (removed)
and one test, which can use StopProfilerThread() instead
- Remove 'paused' state which was only used by the above
- Remove 'engage' state. There is no reason we need this as along as
users keep track of Engage/Disengage calls
Drive-by cleanup:
- Remove import of log.h from profile-generator.h
- Remove unnecessary includes of log.h

Only log incrementally deserialized maps with --trace-maps instead of
iterating the whole heap and print all existing maps on every partial
deserialization for new contexts. This should greatly improve
performance of --trace-maps on websites with many iframes.
- Add helpers to share code: LogNewObjectEvents, LogScriptEvents,
LogNewMapEvents
- Link AllocationSites before any GC

IIFE`s within a function are not guaranteed to be executed only once.
They can be called multiple times and compiler can inline them.
