This prepares removing the special timeout of 200 on the bots. First
we temporarily set 200 on v8 side to remove the flag on the infra side.
Afterwards we'll remove the v8-side code, tested in CQ.

- Change the input type to a AllocationSpace rather than int given the

Space::name() now returns a lower case result but this is only used by
functions guarded by gc_verbose or trace_fragmentation so I don't think
this will break anything.

When using number fuzzer on mjsunit, we add a JS file that

Checking intrinsic state is not feasible on the number fuzzer and in
the past, we needed to skip tests on demand, which is a maintenance
burden. The main function of the fuzzer, to check for dcheck errors and

for MSAN failures.
Interrupt budget was store in bytecode array and used to be shared
across all contexts. With lazy feedback allocation, using context
independent interrupt budget might lead to performance cliffs when
we have closures that do not share the same feedback (for ex: across
contexts). This would be a problem even earlier but it could be
more pronounced with feedback vector allocation, since the budgets
for optimization is much higher (144x) than the budget for feedback
allocation.

Since wasm optimizations are independent of JS optimizations, we can
just combine the "no_liftoff" variant with the existing "stress"

a "Liftoff only" variant as part of "nooptimization".
This gives more coverage to find bugs like https://crrev.com/c/1543354

For standard test failures, the variant name is enough to deduce the
full command line of the test. This is used to create the flako
command line on the infra side.
Test failures from numfuzz have additional variant_flags, calculated
by the fuzzer, which don't match a variant name. Exposing those in
the test results will enable printing a proper flako command line
on infra side for numfuzz cases.

Allocate feedback vectors lazily when the function's interrupt budget has
reached a specified threshold. This cl introduces a new field in the
ClosureFeedbackCellArray to track the interrupt budget for allocating
feedback vectors. Using the interrupt budget on the bytecode array could
cause problems when there are closures across native contexts and we may
delay allocating feedback vectors in one of them causing unexpected
performance cliffs. In the long term we may want to remove interrupt budget
from bytecode array and use context specific budget for tiering up decisions
as well.

This change significantly improves the performance of string
concatenation in optimized code for the case where the resulting string
is represented as a ConsString. On the relevant test cases we go from
serializeNaive: 10762 ms.
serializeClever: 7813 ms.
serializeConcat: 10271 ms.
to
serializeNaive: 10278 ms.
serializeClever: 5533 ms.
serializeConcat: 10310 ms.
which represents a 30% improvement on the "clever" benchmark, which
tests specifically the ConsString creation performance.
This was accomplished via a couple of different steps, which are briefly
outlined here:
1. The empty_string gets its own map, so that we can easily recognize
and handle it appropriately in the TurboFan type system. This
allows us to express (and assert) that the inputs to NewConsString
are non-empty strings, making sure that TurboFan no longer creates
"crippled ConsStrings" with empty left or right hand sides.
2. Further split the existing String types in TurboFan to be able to
distinguish between OneByte and TwoByte strings on the type system
level. This allows us to avoid having to dynamically lookup the
resulting ConsString map in case of ConsString creation (i.e. when
we know that both input strings are OneByte strings or at least
one of the input strings is TwoByte).
3. We also introduced more finegrained feedback for the Add bytecode
in the interpreter, having it collect feedback about ConsStrings,
specifically ConsOneByteString and ConsTwoByteString. This feedback
can be used by TurboFan to only inline the relevant code for what
was seen so far. This allows us to remove the Octane/Splay specific
magic in JSTypedLowering to detect ConsString creation, and instead
purely rely on the feedback of what was seen so far (also making it
possible to change the semantics of NewConsString to be a low-level
operator, which is only introduced in SimplifiedLowering by looking
at the input types of StringConcat).
4. On top of the before mentioned type and interpreter changes we added
new operators CheckNonEmptyString, CheckNonEmptyOneByteString, and
CheckNonEmptyTwoByteString, which perform the appropriate (dynamic)
checks.
There are several more improvements that are possible based on this, but
since the change was already quite big, we decided not to put everything
into the first change, but do some follow up tweaks to the type system,
and builtin optimizations later.

After introducing the new pointer-containing Object class in V8 (see
https://docs.google.com/document/d/1_w49sakC1XM1OptjTurBDqO86NE16FH8LwbeUAtrbCo/edit),
gcmole stopped finding errorneous usage of raw pointers in functions that could
trigger GC. This CL modifies the heuristics of the tool to classify Object and
MaybeObject instances as raw pointers, thus giving back the missing warnings.
Updated the gcmole implementation to support modern llvm (tested with llvm 8.0)
for which additional support for MaterializeTemporaryExpr, ExprWithCleanups and
UnaryExprOrTypeTraitExpr was needed.
Basic tests are added to make it harder to introduce such errors without
noticing in the future.

In the early days of Chrome when we used WebKit there was no support for
ASCII strings on the C++ side, so we put a hint onto these two-byte
strings that said "string only contains one byte data", such that
internally in V8 when these were involved in string operations, we could
instead create the *cheaper* one byte strings.
Nowadays Blink properly supports one-byte string representations and
this additional hint only comes with overhead, since we check it in
quite a few places (i.e. on the hot path for string concatenation), plus
we end up consuming more memory due to the additional string maps.
Removing the hint also frees one bit in the InstanceType zoo for
strings.
This alone improves performance on the `bench-dom-serialize.js` test case
by around **3%**.

The initial prototype consists of a few parts:
The VS Code extension is now built using TypeScript. The build artifact
is checked-in along side the extension. The extension now starts up
the language server when it is activated. The path to the LS
executable is configurable via VS Code settings.
The language server is a separate executable. It adds a light-weight
object model on top of a Json Parser for reading/writing LSP requests
and responses. The current server is very much bare-bones featurewise:
- Tell the client that the server can handle "goto definition"
- Recompile when Torque files change
- Goto definition support for Macros/Builtins, local variables
and arguments.

In the Crankshaft days we (mis)used the Representation to also express
the various internal representations that the compiler understands. But
with TurboFan we now have proper MachineRepresentation and MachineType,
which do that independently. So there's no need to have this in the
Representation class anymore, and instead the Representation class only
needs to deal with the field representations.

The StackTraceFrame object will be used in a future CL to replace
StackFrameInfo as the object returned by the inspector API, as well
as the object used in the stack_frame_cache.
The object itself is a simple wrapper around a reference to a
FrameArray plus an index, as well as a reference to a
StackFrameInfo object that will get lazily initialized.
This is the first step towards unifying stack trace representation

V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.
This CL converts the test-suites to load tests during the test run in parallel.
After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.
This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

This replaces the "trusted" with the "jitless" correctness-fuzzing experiment.

This reverts commit 6e03d7ee42.
Reason for revert: This breaks the Android bot:
https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Android%20Arm64%20-%20N5X/2933
It's quite hidden due to https://crbug.com/v8/8731 but all shards
time out. It looks like to to this change, testing takes
dramatically longer, maybe the pushing takes now much longer than
before. If we want decide for this, the builder needs to get
many more shards.

Class positions is a struct that stores the start and end positions of a class
literal. It is stored both on class objects, and the template used to
instantiate class objects.
The template is reachable from the bytecode array and therefore serialized by
the startup serializer. Class objects are context-dependent and therefore
serialized by the partial serializer. Serializing class positions from both
serializers violates the assumption that we don't serialize any object twice.
