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.

The JSNativeContextSpecialization class is getting rather huge with all

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.

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

Removes a branch that checks for a condition that has been checked on dominators of the branch.
This introduces a new reducer that propagates the list of checked conditions (and their boolean values) through the control flow graph. If it encounters a branch checking a condition with a known value, the branch is eliminated.
The analysis relies on loops being reducible: if a condition has been checked on all paths to loop entry, then it is checked in the loop (regardless what of the conditions checked inside the loop).
The implementation is fairly naive and could be improved:
- all the operation on the condition lists could be made allocation-free when revisited.
- we could try to use a map structure rather than a linked list (to make
lookups faster).
- the merging of control flow could be changed to take into account
conditions from non-dominating paths (as long as all paths check
the condition).

Introduce a new JSGlobalSpecialization advanced reducer that runs
during the initial inlining and context specialization, and specializes
the graph to the globals of the native context. Currently we assume
that we do not inline cross native context, but long-term we will grab
the global object from the JSLoadGlobal/JSStoreGlobal feedback (with the
new global load/store ICs that are currently in the workings), and then
this whole specialization will be fully compositional even across
cross-context inlining.
Note that we cannot really handle most of the stores to global object
property cells because TurboFan doesn't have a mechanism to enforce
certain representations. Also note that we cannot yet fully benefit
from the type feedback collected on the global object property cells,
because the type system cannot deal with maps in a reasonable way.

Some highlights of changes:
* TurboFan's RegisterConfiguration class moved to V8's top level

* Various "ToAllocationIndex" and related methods removed.
* Code that can be easily shared between Register classes on
different platforms is now shared.
* The list of allocatable registers on each platform is declared
