CodeKind::OPTIMIZED_CODE -> TURBOFAN
Kinds are now more fine-grained and distinguish between TF, TP, NCI.
CodeKind::STUB -> DEOPT_ENTRIES_OR_FOR_TESTING
Code stubs (like builtins, but generated at runtime) were removed from
the codebase years ago, this is the last remnant. This kind is used
only for deopt entries (which should be converted into builtins) and
for tests.

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.

Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

This replaces all typedefs that define types and not functions by the

Patchset 2 then adds some manual changes for typedefs for pointer types,

of arguments (which is one more now, temporarily), just forward all
arguments down via MacroAssembler and TurboAssembler to
TurboAssemblerBase.
Interestingly, this requires more specific types sometimes (int instead
of size_t), since further down the forwarding chain, the compiler does
not recognize any more that the value is a constant, and emits a
warning about a possibly truncating implicit conversion.

The platform specific macro assembler headers can not be included
directly. They require symbols declared in macro-assembler.h.
We also cannot include macro-assembler.h from the platform specific
headers, because that would form a cycle, and the include in
macro-assembler.h would be skipped, which then also fails.
This CL documents and enforces this unfortunate situation.
This helps with further iwyu cleanups.
Note that current code which includes the platform specific headers
only works because we transitively included macro-assembler.h already
before.

the assemblers's dependency on isolates, and there is now only one
way to create an Assembler, which is to use the options.
Note that some operations on assemblers still need an isolate, such
as GetCode(), and in these cases, the isolate is an additional
argument to the method.

There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.
This saves about 20KB of binary size on x64.

This ensures that there is only one entrance point from C++ to
generated code, hence only one method has to be excluded from CFI.
It also introduces type safety by only allowing the code to be called
with the right arguments.
This CL includes minor drive-by fixes in the tests, like removing
unused dummy variables.

This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.
Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.
Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.
