Notes:
- We use simple recursion to keep track of how many "new" operators we have seen
  and where.
- This makes the self-baked stack class PositionStack in parser.cc unnecessary.

allow_natives_syntax() which was already in ParserBase.
- This CL also decouples (Pre)ParserTraits better from (Pre)Parser, passing more
information as parameters, so that the Traits don't need to get it from

Improve positions tracking inside the HGraphBuilder.

Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

V8 Microtask Queue & API

This patch generalizes Object.observe callbacks and promise resolution into a FIFO queue called a "microtask queue".

It also exposes new V8 API which exposes the microtask queue to the embedder. In particular, it allows the embedder to

-schedule a microtask (EnqueueExternalMicrotask)
-run the microtask queue (RunMicrotasks)
-control whether the microtask queue is run automatically within V8 when the last script exits (SetAutorunMicrotasks).

Refactor scope and function state tracking in (Pre)Parser.

Notes:
- PreParser::Scope was a weird combination of Parser::FunctionState and
  Scope. Split it into two (PreParser::FunctionState and PreParser::Scope). This
  is necessary for unifying the Parser and the PreParser.
- Scopes take care of language mode and tracking "with".
- FunctionStates take care of counting material literal indexes, properties
  etc. and tracking generators.
- PreParser::Scope::InsideWith was a hack to make a FunctionState-like object
  take care of tracking "with". It's now the responsibility fo PreParser::Scope
  and Scope.
- PreParser::ScopeType is unnecessarly, there is already a ScopeType enum in
v8globals.h.
- Renamed scope stack variables so that they're consistent in Parser and PreParser.
- Parser::FunctionState and Parser::BlockState had an unnecessary dependency to
  the Parser; they only need a couple of things from Parser. Broke the
  dependency.
