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.

We are creating a lot of tags. The result is that git 'packs'
some of them. Our parsers in the release script cannot handle
this.

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.

This adds some initial support for keyed element access to fast,
non-holey JSArray objects.
Also renames PropertyAccessInfoFactory to AccessInfoFactory and
PropertyAccessMode to AccessMode.

This is currently hardcoded in the infra-side test runner
setup, but will be removed there, so that swarming triggers
don't need a custom environment.

Rename ZoneTypeCache to TypeCache and use a single shared (immutable)
instance consistently to cache the most commonly used types. Also serves
as a chokepoint for defining those types, so we don't repeat the
definition (and possible bugs) in various places.

Both the JSTypeFeedbackSpecializer and the JSTypeFeedbackLowering is
dead code by now, since the more general JSNativeContextSpecialization
deals with the property/global load/store type feedback in a way that
also interacts properly with inlining.

When eagerly parsing arrow functions, expressions in default
parameter initializers are parsed in the enclosing scope,
rather than in the function's scope (since that scope does not
yet exist). This leads to VariableProxies being added to the
wrong scope, and scope chains for FunctionLiterals being incorrect.
This patch addresses these problems by adding a subclass of
AstExpressionVisitor that moves VariableProxies to the proper
scope and fixes up scope chains of FunctionLiterals.
This is a revert of the revert https://crrev.com/e41614a058426fb6102e4ab2dd4f98997f00c0fc
with a much-improved (though not yet perfect) Scope::ResetOuterScope
method which properly fixes not only the outer_scope_ pointer but also
fixes the inner_scope_ list in the relevant outer_scopes.
More work likely still needs to be done to make this work completely,
but it's very close to correct.
