static_assert without message, instead of our STATIC_ASSERT macro.

This prevents ambiguity errors in C++20 due to ADL when casting types in

While the overall goal of this commit is to change deoptimization
entries into builtins, there are multiple related things happening:
- Deoptimization entries, formerly stubs (i.e. Code objects generated
at runtime, guaranteed to be immovable), have been converted into
builtins. The major restriction is that we now need to preserve the
kRootRegister, which was formerly used on most architectures to pass
the deoptimization id. The solution differs based on platform.
- Renamed DEOPT_ENTRIES_OR_FOR_TESTING code kind to FOR_TESTING.
- Removed heap/ support for immovable Code generation.
- Removed the DeserializerData class (no longer needed).
- arm64: to preserve 4-byte deopt exits, introduced a new optimization
in which the final jump to the deoptimization entry is generated
once per Code object, and deopt exits can continue to emit a
near-call.
- arm,ia32,x64: change to fixed-size deopt exits. This reduces exit
sizes by 4/8, 5, and 5 bytes, respectively.
On arm the deopt exit size is reduced from 12 (or 16) bytes to 8 bytes

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.

it difficult to use and add any new ones. Large chunks of code were also
duplicated across TryNewCode and NewCode. The previous CL
(https://chromium-review.googlesource.com/c/v8/v8/+/1585736) added a new
CodeBuilder class which allows much simpler building of Code objects.

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.

With ReadOnlyRoots and GetIsolate on JSReceiver, we can remove almost
every isolate parameter from <Object>::Print. The remaining ones, like
Map, are special-caseable for read-only maps, and as a result we can
remove isolate parameters from <Object>::Print entirely.
This patch also opportunistically cleans up a few places where isolates
were only needed for Object::Print, such as TransitionAccessors and
DescriptorArrays.

Commit edec05ea73
Usage of Print function was not consistent with it's signature,
which caused failures in compilation.
Original commit message:
`All Object::Print functions now take an Isolate* parameter. Various
XX::XXPrint functions now take an Isolate if it's needed rather than
calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather
than DECL_PRINTER.
The _v8_internal_Print_ function (intended for use in gdb) now uses
Isolate::Current() to get hold of an Isolate.
Reduces the GetIsolate and GetHeap count by 9 and 5 respectively.
Also removes unneeded gdb/lldb macros (along with their support
functions), jfv, jfm, jda and jta, since job does the same thing.`
