This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.

Make off-thread deserialization play well with the Isolate compilation
cache, by moving the Finish call into GetSharedFunctionInfoForScript.
This means that
a) The isolate cache is checked before the Finish, allowing it to be
hit, and
b) Results of off-thread deserializations are written into the Isolate
cache.

The adding of base:: was mostly prepared using git grep and sed:
git grep -l <pattern> | grep -v base/vector.h | \
xargs sed -i 's/\b<pattern>\b/base::<pattern>/

v8::internal::base::Vectors.

- Renames StackParameterCount to ParameterSlotCount, to avoid
confusion between slots and parameters, which are not in general
equivalent.
- Similarly, renames StackReturnCount to ReturnSlotCount.
- Adjusts the result of GetFirstUnusedStackSlot to return one more
than the last slot of the argument area, not including padding.
- Renames GetFirstUnusedStackSlot to GetOffsetToFirstUnusedStackSlot
to reflect that the result is an offset from callee to caller
frames.
- GetReturnsOffset is a little clearer, with adjustment for the
different semantics of GetFirstUnusedStackSlot.
- Renames 'optional_padding_slot' and 'first_unused_stack_slot'
variables in Tailcall codegen to reflect that these are offsets.

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.

Strictly speaking there are some left in api.cc, but they are in
deprecated functions with non-deprecated alternatives.
Apart from changes made using tooling, this also modifies
FieldType::AsClass to return Map* rather than Handle<Map> and converts
its call sites to create the Handle when they need it - currently
several sites immediately dereference the Handle.
Also marks WasmDebugInfo as NeverReadOnlySpaceObject so GetIsolate and
GetHeap remain usable.

Currently each isolate stores its own array of
{CallInterfaceDescriptorData}. This array has size 173, and each entry
has 40 bytes. That's already 7kB per isolate.
Additionally, each {CallInterfaceDescriptorData} allocates two
heap-allocated arrays, which probably add up to more than the static
size of the {CallInterfaceDescriptorData}. Note that all the
{CallInterfaceDescriptorData} instances are initialized eagerly on
isolate creation.
Since {CallInterfaceDescriptor} is totally isolate independent itself,
this CL refactors the current design to avoid a copy of them per
isolate, and instead shares them process-wide. Still, we need to free
the allocated heap arrays when the last isolate dies to avoid leaks.
This can probably be refactored later by statically initializing more
and avoiding the heap allocations all together.
This refactoring will also allow us to use {CallInterfaceDescriptor}s
from wasm background compilation threads, which are not bound to any
isolate.

With the Ignition + Turbofan pipeline there is very little overlap between the data
needed for unoptimized compilation and optimized compilation. As a result, it is
cleaner to split up the CompilationInfo into UnoptimizedCompilationInfo and
OptimizedCompilationInfo.
Doing so also necessitate splitting up CompilationJob into UnoptimizedCompilationJob
and OptimizedCompilationJob - again there is not much overlap so this seems cleaner.

Rather than having a single script compilation timer, split it into
multiple timers depending on the state of the (blink-owned) code cache
and (v8-owned) complation cache. This is intended to replace both the
script compilation time timer, and the compilation heuristic enum.
Also keep track of why blink might not want us to produce (or consume) a
code cache, and split the compilation timer on this as well.
Note, there is currently no timer for streaming sources, so these won't
show up in the histograms.

Primitive values, which the embedder can use to store metadata.
The HostDefinedOptions is passed to V8 through the ScriptOrigin, and
passed back to the embedder through HostImportModuleDynamically for
module loading.

Don't hold a pointer to parse_info in compilation_info, and instead explicitly
add the fields needed in compiation_info. The intention is to make ParseInfo
only actually needed for parsing, and eventually make it possible to compile
with only a CompileInfo.

Removes the SharedFunctionInfo field from the ParseInfo structure. Instead
require a SharedFunctionInfo to be explicitly passed to ParseFunction.
Also renames GetUnoptimizedCode to CompileUnoptimizedFunction to make it
clear it should only be called for non-top-level code.

Callables for TF builtins are autogenerated and accessible through
Builtins::CallableFor. This removes the manually written accessors from
CodeFactory.

A step towards removing isolate from ParseInfo.
Removing isolate from ParseInfo will make it easier to create and
execute parse tasks on background threads.
