77d06401ad Take ast node id counting away from Isolate. 
When we're going to parse multiple scripts in parallel, we cannot have the
Isolate count the ast node ids.

Now the counter is stored in CompilationInfo instead. This is because we need to
add ast nodes after parsing too.

e5081792f9 Initial support for debugger frame state in Turbofan. 
Bunch of changes were necessary:
- refactor attaching the frame states/lazy bailouts in AstGraphBuilder
  (essentialy reland of r23096),
- attaching frame state to some JS nodes in a similar way to attaching
  context (this is quite ugly and we should take another look at this),
- new bailout point for the debugger statement,
- register allocation constraints for the frame states,
- generating translations and deopt entries, attaching them to
  safepoints,
- enabled one mjsunit test for debugger state that uses the generated
  frame state.

ad3a1a99d3 Refactor parser Checkpoints. 
Why this is better:

1) Not needing an extra template parameter for Checkpoints ctors. This was
especially confusing since the template parameter was named Parser and Parser is
also used as a type name and is also a concrete type. This CL makes it clear
that ParserTraits::Checkpoint is consturcted with ParserBase<ParserTraits> -
that's the only sensemaking type for the ctor param anyway.

2) This CL makes ParserBase define a Checkpoint base class (which knows how
to create and restore a checkpoint with ParserBase) which
PreParserTraits::Checkpoint and ParserTraits::Checkpoint inherit, and not the
other way around.

This is a more intuitive way to implement the "base functionality + extending
it" concept than the previous solution. The previous solution was to allow
Traits to define a Checkpoint class and make ParserBase<Traits>::ParserCheckpoint
(which defines the base functionality) inherit from it.

3) This CL moves the Checkpoint class definitions out of the SomeTraits::Type
struct; SomeTraits::Type is supposed to be a collection of typedefs and not
contain anything else.

Checkpoints were introduced in r22925 ( https://codereview.chromium.org/443903003 ).

The attached test can detect this error, but the test relies on a broken

d62b71e97c Modify SizeOfFirstPage to take ool constant pool into account. 
The OOL constant pool places constants in the old pointer space rather than the code space
which makes test-heap/ReleaseOverReservedPages fail. Modify SizeOfFirstPage to
increase the initial size of old-pointer space by the size of the constant pool and
decrease the code space by a corresponding amount.

b80e76841e Remove a brittle assertion from Turbofan lazy deoptimization handling.

However, there are exceptions - such as nop or constant pool in-between being fine - that make the assertion brittle.

670df5063b Implement representation selection as part of SimplifiedLowering. Representation selection also 
requires inserting explicit representation change nodes to be inserted in the graph. Such nodes
are pure, but also need to be lowered to machine operators. They need to be scheduled first, to
determine the control input for any branches inside.

This CL requires extensive testing. More tests to follow.
