If a caller starts the sampling heap profiler and takes a snapshot, and
then deletes the snapshot before the sampling has completed, a
use-after-free will occur on the StringsStorage pointer.
The same issue applies for StartTrackingHeapObjects which shares the
same StringsStorage object.

This introduces Word64 support for the CheckBounds operator, which now
lowers to either CheckedUint32Bounds or CheckedUint64Bounds after the
representation selection. The right hand side of CheckBounds can now
be any positive safe integer on 64-bit architectures, whereas it remains
Unsigned31 for 32-bit architectures. We only use the extended Word64
support when the right hand side is outside the Unsigned31 range, so
for everything except DataViews this means that the performance should
remain the same. The typing rule for the CheckBounds operator was
updated to reflect this new behavior.
The CheckBounds with a right hand side outside the Unsigned31 range will
pass a new Signed64 feedback kind, which is handled with newly introduced
CheckedFloat64ToInt64 and CheckedTaggedToInt64 operators in representation
selection.
The JSCallReducer lowering for DataView getType()/setType() methods was
updated to not smi-check the [[ByteLength]] and [[ByteOffset]] anymore,
but instead just use the raw uintptr_t values and operate on any value
(for 64-bit architectures these fields can hold any positive safe
integer, for 32-bit architectures it's limited to Unsigned31 range as
before). This means that V8 can now handle huge DataViews fully, without
falling off a performance cliff.
This refactoring even gave us some performance improvements, on a simple
micro-benchmark just exercising different DataView accesses we go from
testDataViewGetUint8: 796 ms.
testDataViewGetUint16: 997 ms.
testDataViewGetInt32: 994 ms.
testDataViewGetFloat64: 997 ms.
to
testDataViewGetUint8: 895 ms.
testDataViewGetUint16: 889 ms.
testDataViewGetInt32: 888 ms.
testDataViewGetFloat64: 890 ms.
meaning we lost around 10% on the single byte case, but gained 10% across
the board for all the other element sizes.

Calls to StartTickSample() and FinishTickSample() are not permitted by
multiple producers. If the signal handler interrupts the main thread,
both might receive the same pointer into the circular buffer and one
will overwrite the data of the other.
This means we cannot call it in tests, and have to use AddSample()
instead.

important goals to be realized: 1) we can easily stringify individual
frames and 2) we can (if needed) call back into JS from this callback
with a usable structure. If, as is sometimes the case, a v8::StackTrace

that is passed to PrepareStackTraceCallback.

This CL adds OnFailure::DUMP_ON_FAILURE representing a scope where base::
DumpWithoutCrash is called when V8 execution is detected. As V8 can't call base
functions, this CL also adds Platform::DumpWithoutCrash.

This method only recorded stats of the generated code object. Since
both counters that are updated are thread-safe anyway, we can just
update them from the background instead (during {ExecuteCompilation}).

And remove the TurboFan/Liftoff specific {FinishCompilation}
implementations completely. Compilation errors are now stored in the
{WasmCompilationUnit} directly as a {Result<WasmCode*>}. They are
retrieved via {WasmCompilationUnit::ReportError}, which moves the error
to the {ErrorThrower}.
This prepares more changes to completely remove the {FinishCompilation}
phase.

Previously, this was just a field on the WasmResult, which is not
allowed according to the style guide.
A special r-value accessor for the value is needed for the cases where
the contained type is not copyable, e.g. unique_ptr.

Headers are not included in jumbo builds so excluding
them has no meaning and will cause problems in a future
version of jumbo. This patch removes two such headers.
