d1b27019d3 [include] Split out v8.h
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.

87c81250cc [test] Skip parallel compile tasks tests under off-thread
It is becoming difficult to continue supporting the compiler dispatcher
and background compile task unittests alongside the off-thread
finalization work, so disable those tests when that flag is enabled.

7f2d66cd98 [offthread] Disable compiler dispatcher tests
Disable the BackgroundCompileTask and CompilerDispatcher unittests when
--finalize-streaming-on-background is enabled. The inner function API to
concurrent compilation doesn't yet support off-thread finalization, so
these tests break under that configuration.

6458a5296b [compile] Add an UnoptimizedCompileState class
Move the persistent compilation state and Isolate inputs (such as the
allocator, shared AST constants, hash seed, logger, etc.) which survives
across both parse and compile, out of ParseInfo and into a new
UnoptimizedCompileState class. Also add UnoptimizedCompilePerThreadState
for per-thread state such as stack limit and RCS.

In particular, this new state survives the ParseInfo being destructed,
which means it is available after off-thread finalization. This allows a
followup to access the PendingCompilationErrorHandler after finalization
and report errors on merge.

9b986bf97c [objects] Use function syntax kind enum instead of bits on SFI and ParseInfo
- Rename FunctionLiteral::FunctionType to FunctionSyntaxKind.

- Re-express IsWrappedBit, IsDeclarationBit, IsAnonymousExpressionBit,
  and IsNamedExpressionBit in SFI::flags as FunctionSyntaxKind. This
  frees up 1 bit in SFI::flags.

- Re-express the analogous bits in ParseInfo as FunctionSyntaxKind.

- Simplifies some logic in the back-and-forth passing of this info
  between SFI and ParseInfo.

- Drive-by fix parsing class member initializations as kAccessorOrMethod.

f92d7196b9 [SFI] Always store function_literal_id in SFI.
Calling FindIndexInScript performs a linear search on the script functions and can
take considerable time. With Bytecode flushing we will lose the function_literal_id
and have to call FindIndexInScript if we ever recompile the flushed function. This
can take a significant proportion of the recompilation time and has caused regressions
in rendering times for some web applications (e.g, 395ms in FindIndexInScript for 132ms
spent lazily re-compiling code).

To avoid this, add function_literal_id back into the SFI and remove it from
UnoptimizedCompileInfo. This will slightly regress memory usage (particularly
in cases where many of the SFIs are compiled), however it means we can remove
the FindIndexInScript function and avoid these long-tail regressions when
bytecode is flushed.

43cd5d1054 [tracing] Speed up SharedFunctionInfo::TraceID
Avoid the linear lookup of function literal id when getting the shared
function info TraceID, by optionally passing through a FunctionLiteral.
Additionally, use the FunctionLiteralId helper when a FunctionLiteral is
not available, since it can also fast-path in some cases.

As a drive-by, allow using a ScriptIterator without an Isolate pointer
(e.g. manually creating a handle) to allow calling FunctionLiteralId
without an Isolate pointer.
