Load mjsunit.js inside the realm as otherwise the functions are not
available in the realm's scope.
This also prints timestamps after each test to easier track down slow
tests.
We also pass --omit-quit to not stop too early.
This also adds the ability to skip certain tests for endurance
fuzzing and skips some tests with known problems.

Original Commit Message:
The original CL introduced a test which uses a random number generator.
I disable the test for now, which is okay because this CL adds to a
work-in-progress feature anyways, and I will fix the problem in another
CL.
Original description:
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.

1. Detecting OSR in tests -- replaced with a stack walk in
%GetOptimizationStatus
2. Naming optimization log files -- replaced with the
optimization id
This allows us to remove a field from the SFI, moving the
bailout reason into the counters field.
As a drive-by, add optimization marker information (e.g.
marked for optimization) to the optimization status.

Note that the previous prototype for catch and throw have been marked

Different Intl features (DateTimeFormat, NumberFormat, etc) have
different lists of locales supported. Previously, the default locale

system, if any of these features was missing data. With this patch,
only that feature is set to "und". In this way, the data quality should
be just as good as if there were no fallback logic, but at the same time,
resolvedOptions().locale should show the locale actually in effect.

This patch implements a timezone backend which is based on ICU, rather
than operating system calls. It can be turned on by passing the
--icu-timezone-data flag. The goal here is to take advantage of ICU's
data, which is more complete than the data that some system calls expose.
For example, without any special code, this patch fixes the time zone
of Lord Howe Island to have a correct 30 minute DST offset, rather than
60 minutes as the OS backends assume it to have.
Unfortunately, the parenthized timezone name in Date.prototype.toString()
differs across platforms. This patch chooses the long timezone name,
which matches Windows behavior and might be the most intelligible, but
the web compatibility impact is unclear.

The function "foo" in "base_getter_test" was picking up a left-over
optimised code object from foo's code map, the third time that
base_getter_test was run, instead of optimising it itself. This
broke the assumptions of the test, that each case was functionally
independent from the others, and had started off with empty feedback

This breaks the test though, so we have to blacklist it pending a fix

The reason:
The CL #41255 (https://codereview.chromium.org/2520363002 ) reimplemnt the Number.prototype.toString and the added number-tostring test cases failed at x87.
Similar to many previos fixing CLs, i.e.: CL #37371 (https://codereview.chromium.org/2111493002 ), the root reason is:
The Gcc compiler and it's dependent C++ libraris on linux platform use x87 in extended 80-bit double precision by default.
So the reimplemented DoubleToRadixCString() will generate extended 80-bit double precision result which isn't the expected standard 64-bit double precision
value.
Although modifying DoubleToRadixCString() function to manually do the 80-bit <--> 64-bit conversion for each double/float computation step can fix this issue,
but it wll drop the DoubleToRadixCString() function's performance of other architectures.
This CL put the failed number-tostring test cases into number-tostring-big-integer.js and disables it for x87.

This CL further extends the debug wrapper, migrates around 60 tests, and
removes a few tests that use functionality we will not support anymore.
In more detail:
* Removed tests that use:
* enable/disable individual breakpoints
* invocationText()
* the ScriptCollected event
* showBreakPoints
* evalFromScript (and similar)
* mirror.constructedBy and mirror.referencedBy
* event_data.promise()
* Some frame.evaluate uses were adapted since due to differences between
remote objects (inspector) and mirrors. For instance, exceptions are
currently not recreated exactly, since the inspector protocol does not
give us the stack and message separately. Other objects (such as
'this' in debug-evaluate-receiver-before-super) need to be explicitly
converted to a string before the test works correctly.
* Ensure that inspector stores the script before sending ScriptParsed and
ScriptFailedToParse events in order to be able to use the script from
within those events.
* Better remote object reconstruction (e.g. for undefined and arrays).
* New functionality in wrapper:
* debuggerFlags().breakPointsActive.setValue()
* scripts()
* execState.setVariableValue()
* execState.scopeObject().value()
* execState.scopeObject().property()
* execState.frame().allScopes()
* eventData.exception()
