The ECMA 402 implementation previously pushed directly to real
Arrays, which risks having observably incorrect behavior in the
presence of monkey patching. This patch uses InternalArrays instead
to avoid that hazard.

This adds ignition to the testing variants that are run on all
bots.
Failing tests can only be skipped with the NO_IGNITION
keyword in status files. Existing expectations for the
ignition_turbofan variant are all duplicated and use the
NO_IGNITION keyword as well now.

When exporting `shared-library` in profile log, additionally export a
slide offset. This is required to parse profile logs generated on
systems with ASLR (OS X), otherwise it is impossible to assign C++
symbol names to their addresses in the log.

This adds a dedicated flag for enabling the BytecodeGraphBuilder. The
intention is to be explicit when this variant is being tested and to
avoid unnecessary overhead in production code for a configuration that
is not yet shipping.

This commit introduces IgnitionStatisticsExtension, which provides
methods for accessing Ignition statistics and counters from JavaScript.
The extension is registered when FLAG_ignition and
FLAG_trace_ignition_dispatches are both enabled.
For the moment, the only exposed function is
getIgnitionDispatchCounters(), which allows to retrieve Ignition
dispatch counters as a JavaScript object.
