This makes sure that --hydrogen-filter only filters for Crankshaft, not
for TurboFan compilations. For TurboFan there is --turbo-filter as a
separate flag already. There no longer is a single flag to filter both
compilers at the same time, one can still specify both flags however.

We had exactly one test case for --noturbo-types, so it's likely that
the generic pipeline (without types) was already broken for quite some
time, plus no one expressed interest in maintaining it, plus it
complicates the JSGenericLowering integration. So decision is to kill
it.

Function bindings are the only variables in LEGACY_CONST mode.
(https://codereview.chromium.org/1819123002/). Since these variables
can also be accessed in strict mode functions we should support
handling such variables. Assigning to a legacy constant throws
a TypeError in strict mode. Also fixes hydrogen.cc to throw a
TypeError for legacy constants.

This removes the "AboutToRun" callback. It makes not much
sense as it is not actually called before a test is run,
but just before the results are retrieved from the results
queue. Therefore, from an information-value p-o-v it is
redundant to the "HasRun" callback.

This also reduces log size on the bots by 50%, in order to
reduce buildbot slowness, which is tied to the amount
of logs.

When FLAG_trace_ignition_dispatches is enabled, a dispatch counter is
kept for each pair of source-destination bytecode handlers.

Each counter saturates at max uintptr_t value.

Counters are dumped as a JSON-encoded object of objects, such that
each key on the top level object is a source bytecode name, and each key
on the corresponding value is a destination bytecode name, with the
associated counter as value. The output file name can be controlled
with the FLAG_trace_ignition_dispatches_output_file flag.

The JSON file may be written by calling
Interpreter::WriteDispatchCounters(), which is done for d8 in
Shell::OnExit, if FLAG_trace_ignition_dispatches is enabled.

This refactors the OptimizedCompileJob class to be agnostic from the
actual underlying compiler. Instead it represents a base class for all
compilation jobs. The implementation is provided by the backend by just
overriding the phase methods.

Also note that this contains the semantics change of not falling back to
Crankshaft when TurboFan optimization fails. This fallback is no longer
needed and will not be supported going forward.

Reason for revert:
One small issue easily fixed here: https://codereview.chromium.org/1867333003/

But it looks like MSVS 2013 doesn't like some of the formats and exists with the unhelpful:
Stderr:

format specifier", 0)

It's easier to revert for now, I'll dig more into the docs:

https://msdn.microsoft.com/en-us/library/tcxf1dw6(v=vs.120).aspx

And then resubmit, making sure I run these bots.
