The --trace-turbo flag would cause a crash when compiling a WASM_FUNCTION. It
was caused by assuming the OptimizedCompilationInfo had a SharedFunctionInfo
attached if the code isn't a stub and wasm functions are not considered as such.
In order to test this, we've added a new flag to specify were to dump JSON
files: --trace-turbo-path. This is used to make sure we do not leave lots of
files behind in the top-level directory. It should be useful as standalone
feature too.

Code comments are heap-allocated and never freed. We don't want to
attach them to the code object via a finalizer, since that could change
gc timing and heap layout when you enable code comments. They are used
to testing only anyway, so leaking is acceptable here.

The hard-coded timeout in the test is so near, that e.g., adding DCHECKs pushes
the test over the limit. The test is ran with dcheck_always_on=true.
We shouldn't do any performance testing with dcheck_always_on=true; this creates
the wrong incentive to not add DCHECKs (or in this case, CLs which add more
DCHECKs or cause more DCHECKs to be hit cannot land at all).

https://github.com/tc39/ecma262/pull/778 was recently merged
to Ecma 262.
It changes the way to convert between "local time" and UTC in such
a way that it'd work for all timezones whether or not there has
been any change in the timezone offset of the standard time. For
instance, Europe/Moscow and some parts of US state of Indiana have
changed the standard (non-DST) timezone offset a few times. The
previous spec assumes that the the standard timezone offset is
constant, but the new spec take into account the offset change
history.
In addition, it specifies a new way to calculate the timezone
offset during a timezone transition (either in and
out of DST or timezone offset shift).
During a negative transition (e.g. fall backward / getting
out of DST), repeated times are to be interpreted as if the
offset before the transition is in effect.
During a positive transition (e.g. spring forward / getting
into DST), skipped times are to be treated similarly. That
is, they are to be interpreted as if the offset before the
transition is in effect.
With icu-timezone-data, v8 is compliant to the new spec for the
past and the future as well as now whether or not the standard
timezone offset of a given timezone has changed over time
(e.g. Europe/Moscow, Pacific/Apia). With icu-timezone-data,
Australia/Lord_Howe (30 minute DST change) also works per spec.
Without icu-timezone-data, it works only for timezones of which
the standard timezone offset is the same as the current offset
(e.g. most North American timezones other than parts of Indiana)
and of which the DST shift is an hour. For instance, it doesn't work
for Europe/Moscow in 2010 when the standard timezone offset was
+4h because the current (2018) standard timezone offset is +3h. Neither
does it for Lord Howe in Australia with the DST shift of 0.5 hr.

In Promise.all we used to allocate a fresh closure plus a fresh context
for each individual element, which is quite a lot of overhead, especially
since this could be shared in a single context for all elements. The only
bit of information that is needed for each resolve element closure is the
index under which to store the resulting value. With this change we move
this index to the "identity hash" field of the JSFunction, which doesn't
care about the concrete value anyways, as long as it's not zero (the "no
hash" sentinel), and share the rest of the fields in a single outer
context for all resolve element closures.
This limits the maximum number of elements for Promise.all to 2^21 for
now, but that should be fine. Shall we ever see the need for more than
this, we can add machinery to overflow to separate context for indices
larger than 2^21.
This significantly reduces the overhead due to Promise.all on the
parallel-async-es2017-native test, with execution time dropping from
around 148ms to 133ms, so overall a steady 10% improvement on this
benchmark.
