Newer perf.data contains both MMAP and MMAP2 record type,
but MMAP2 record type is not supported in previous ll_prof,
MMAP2 record information will be lost.

Reason for revert:
Unsound use of types in the MachineOperatorReducer. Will work on a sound solution with Fedor.
Original issue's description:

> Merge BinaryOperatorReducer into the MachineOperatorReducer class.
> It does not need `Revisit()` calls, because the newly inserted nodes are

This replaces chromium_roll and the wrapper auto_roll with
just auto_roll. The arguments for the revision to roll and
the last rolled revision are optional and will be
auto-detected (this feature is from the wrapper).
Checking the cq box is default now (as in the wrapper).

The feature sometimes prevents subsequent swarming bots to
delete the work directory on windows.
The data file is not kept on swarming bots anyways, therefore
this switches off the feature completely.

1) Body descriptors moved to their own header files.
2) Missing body descriptors added.
3) Template versions of HeapObject::Iterate*() methods added.
4) Body descriptors support new kind of queries: IsValidSlot(offset) which can be used for invalid slots filtering.
This is a first step towards virtual and static visitors unification and support in-object properties in built-in (sub-)classes.

The JSCallReducer runs together with inlining and tries to strength
reduce JSCallFunction nodes; currently it can fold
Function.prototype.call and Function.prototype.apply (with arguments),
and make it possible to inline across them.
In the case of Function.prototype.apply with arguments we still have to
leave the JSCreateArguments node in the graph because there might be
other (frame state) uses. Once escape analysis is ready, it will take
care of removing these nodes and adding appropriate transitions for the
deoptimizer.

Adds a blacklist of tests which are currently unsupported or broken in Ignition to
the mjsunit and test262 test status.
Also removes --ignition-script-filter flag, and adds a
--ignition_fallback_on_eval_and_catch flag which fallsback to fullcodegen for
functions which call eval or contain a catch block.

The "harmony"-prefixed files have been included in the snapshot for
several releases now, and were only separate originally to enable
loading them via a runtime flag. This patch simply merges them into
the main implementation files for Arrays and TypedArrays, respectively.

The JSNativeContextSpecialization class is getting rather huge with all
the stuff related to property and element access going in. Splitting off
the global object related stuff into JSGlobalObjectSpecialization seems
like a natural separation, especially since the global object
specialization is sort of separate issue anyway. This is neutral
functionality- and performance-wise.

The flake detection is done on the infra-side according to
the contents of the json test results. We don't want the
runner to fail after flakes.
This was controlled on the infra side by accepting any exit
codes so far. After the swarming switch, this is more
difficult, because the runner is wrapped by the swarming
collect script. There, failing exit codes can mean many
things, including network failures. Therefore, we now
force exit code 0 with test failures if those failures
are reported in the formal test results json.
The infrastructure will take care of reporting the flakes
and failures accordingly.
