73c4a61848 (Pre)Parser: Simplify NewExpression handling (fixed). 
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.
- Now the logic is also unified between Parser and PreParser.
- This is a fixed version of r19386.

429ce41f4b Make a single HeapEntry per single JSArrayBuffer data in heap snapshot. 
It turned out that JSArrayBuffer's may share their backing_store so
the backing_store should go through hash map registration just like
other heap objects, so they won't be reported twice.

f6e95dc928 A64 support for DoubleToIStub (truncating). 
Added support for truncating DoubleToIStub and reorganize the macro-assembler
dToI operations to do the fast-path inline and the slow path by calling the
stub.

This a port essentially a port of https://codereview.chromium.org/23129003/.

eaab533fd8 Cleanup the double field tracking in Hydrogen. 
Use a dedicated BuildLoadNamedField() with PropertyAccessInfo,
similar to BuildStoreNamedField() for optimized graph building,
and a dedicated BuildLoadNamedField() for the code stubs, and
don't depend on FLAG_track_double_fields during code generation.

1634631ae4 A64: Tidy up Push and Pop TODOs. 
This addresses several TODOs:
  - Push and Pop requests can be queued up so that arrays of Registers
    can be pushed efficiently, with just one PrepareForPush/Pop.
  - PushMultipleTimes now takes an Operand. This allows variable-length
    arguments arrays to be initialized, for example.
  - A NoUseRealAbortsScope has been added to Abort so that
    AssertStackConsistency can be called from PrepareForPush without
    introducing infinite recursion.

8acefb33fe Test and fix for polymorphic named call deoptimization. 
The fix removes wrong simulates from the number branch of polymorphic
call/field access handling.

The change also fixes the same thing for polymorphic named field
access even thourgh the field access is probably safe in practice
(because it cannot deoptimize). It is better to keep all our simulates
in sync with full codegen.

cd50687b41 (Pre)Parser: Move ParsePrimaryExpression to ParserBase. 
Notes:
- To be able to move the recursive descent functions to ParserBase one at a
time, we temporarily need routing functions from traits to Parser/PreParser,
since the recursive descent functions form a cyclic structure.
- PreParser used to always allow intrinsic syntax. After this CL, it depends on
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
(Pre)Parser.

cad32c1917 (Pre)Parser: Move FunctionState, BlockState and Scope handling to ParserBase. 
Notes:
- This removes Parser::FunctionState and PreParser::FunctionState and adds
ParserBase::FunctionState etc.
- Also the scope stacks and function state stacks are moved to ParserBase.
- PreParser::FunctionState didn't add and subtract
JSFunction::kLiteralsPrefixSize (unlike Parser::FunctionState). Since the
actual value of NextMaterializedLiteralIndex is not used in the Preparser,
this change is valid.
- Traits no longer need functions like is_classic_mode(), since now there is a
 unified way of getting the information from the FunctionState / Scope.

8f170a66e7 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.
