514de317fb [heap] Introduce a conservative stack scanning pass
This CL introduces the mechanism for conservative stack scanning (CSS).
Behind a compile-time flag, it also introduces a CSS pass which scans
the stack during the GC marking phase and marking verification. This
pass is now redundant, i.e., it is not needed for the correctness of
garbage collection. It will be used for experimenting with CSS and for
benchmarking.

31e17fe62d [shared-struct, api] Support shared isolates in API
Currently the ability to create shared isolates is partially exposed to
API. Instead of fully exposing it, this CL makes shared isolate and
shared heap handling transparent to the embedder.

If a flag that requires the shared heap is true (currently
--shared-string-table and --harmony-struct), the first isolate created
in the process will create and attach to a process-wide shared isolate.
Subsequent isolates will attach to that shared isolate. When that first isolate is deleted, the shared isolate is also deleted.

f149912f33 [flags] Protect individual flag updates
Extend the effect of --freeze-flags-after-init to also protect updates
of individual flags instead of only the API.
For this, we wrap each flag in a {FlagValue} class which implicitly
converts to the value of the flag. Some cases still require the explicit
{value()} accessor though. That accessor is {constexpr}, in contrast to
the implicit conversion, because otherwise clang emits a lot of warnings
about dead code within "if (FLAG...)" scopes.

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.

0c2530ffd1 [test] Create one Isolate per unit test (not test suite)
Change the unittests Isolate mixin to create one Isolate per test,
rather than one per test suite. We usually run these tests independently
in separate processes anyway, so this shouldn't affect normal test
execution, but it will avoid Isolate state leaking across tests when
running the unittests binary directly.

Take this opportunity to also clean up the mixins, changing counter
initialization and forcing pointer compression into template traits.

93716b9e71 [snapshot] Add support for native counters.
Counters in generated code, as enabled with --native-code-counters, do not work
in the snapshot. This adds a `v8_enable_snapshot_code_counters` build option
enabled by defaut in debug mode that allows code from the snapshot to increment
the current isolate's set of counters.

For this to work, we need to add native code counters in the external reference
table.

To keep the no snapshot configuration similar, we've also enabled the
--native-code-counters flag by default for debug builds.

ffabcbe8c0 [test] Manually restore changed flags in SaveFlags
SaveFlags previously worked by re-setting the flags using the command
line. Unfortunately, this could reset flags being used by concurrent
processes, which would cause TSAN issues.

Now, SaveFlags stores a copy of the state of all flags on creation, and
only resets changed flags in its destructor. It does this by (ab)using
the flag-definitions.h pseudo-header, adding a new mode to that header
which applies an includer-defined macro to each flag definition.

80195fc58d [Compile] Refactor CompilerDispatcher for inner function compilation jobs
Refactors the CompilerDispatcher to be able to enqueue eager inner functions
for off-thread compilation during top-level compilation of a script.

Unoptimized compile jobs are simplified to only have two phases - compile
and finalization. Only finalization requires heap access (and therefore
needs to be run on the main thread). The change also introduces a requirement
to register a SFI with a given compile job after that job is posted, this
is due to the fact that an SFI won't necessarily exist at the point the job
is posted, but is created later when top-level compile is being finalized.
Logic in the compile dispatcher is update to deal with the fact that a job
may not be able to progress if it doesn't yet have an associated SFI
registered with it.

- Use Microseconds for all RCS timer tests
- Add TestWithContext::SetGlobalProperty helper
- Use explicit v8:: prefix in test-utils.{h,cc}

f6bd23f244 [turbofan] Enforce native context specialization.
There were once plans to generate cross-context code with TurboFan,
however that doesn't fit into the model anymore, and so all of this
is essentially dead untested code (and thus most likely already broken
in subtle ways). With this mode still in place it would also be a lot
harder to make inlining based on SharedFunctionInfo work.
