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.

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.
This CL used to require one of the two ICU CLs below, but not
any more.

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.

Previously GetSharedFunctionInfoForStreamedScript didn't either check the
compilation cache or put the result of compilation into the compilation
cache. This would mean future compiles would need to re-parse / compile
the same script even if the isolate had already seen it. This CL
fixes this.
Also refactors the compilation pipelines to ensure we call debug->OnAfterCompile()
for all script compiles even when loading from a cache.

Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.
So far, only ia32 and x64 are implemented.

In order to test that we don't repeatedly go through the
WasmCompileLazy runtime function, add a flag to the
LazyCompilationOrchestrator to "freeze" it, i.e. disallow any further
lazy compilation.
In tests, use this flag to first call a method, then freeze lazy
compilation, then call the method again to assert that no further lazy
compilation is triggered.
This test currently fails with --wasm-jit-to-native, so disable it for
that variant.

Previously, V8's slice was implemented in a combination of C++ and a
Javascript fallback. The disadvantage of this approach was that the
fast-path required a call through the CEntryStub, which introduced
considerable overhead for small arrays with fast elements kinds.
Now the implementation primarily uses the CSA to generate both the
full spec-complaint implementation as well as fast paths for argument
objects and arrays with fast elements kinds. The CSA implementation
uses a C++ implementation fallback in select situations where the the
complexity of a CSA implementation would be too great and the
CEntryStub overhead is not decisive (e.g. slices of dictionary
elements arrays).
Performance results on semi-random arrays with small number of
elements (old vs. new):
smi copy: 48.7 ms vs. 12 ms
smi slice: 43.5 ms 14.8 ms
object copy: 35.5 ms 7.7 ms
object slice: 38.7 ms 8.8 ms
dictionary slice: 2398.3 ms vs. 5.4 ms
fast sloppy arguments slice: 9.6 ms vs. 7.2 ms
slow sloppy arguments slice: 28.9 ms vs. 8.5 ms
As a bonus, the new implementation is fully spec-compliant and fixes
at least one existing bug.
