dae713f0ad Reapply r10158: Distinguish weak references in heap snapshots, group GC roots. 
[Fixed the bug revealed by the Win32 bot]

Several changes to better organize snapshot data:

1. Provide information about weak references.
2. Group (GC roots) children.
3. Prettify debug snapshot printing.

The full code activated for a function might not be the same code as
is currently the active full code for a function. There where some
asumptions in the debugger preparation for break points.

Unfortunately there is currently no regression test.

08b4262512 Statically check for assignments to const in harmony mode. 
The ES.next draft rev 4 in section 11.13 reads:
It is a Syntax Error if the AssignmentExpression is contained in extended code
and the LeftHandSideExpression is an Identifier that does not statically resolve
to a declarative environment record binding or if the resolved binding is an
immutable binding.

This CL adds corresponding static checks for the immutable binding case.

830f763b07 MIPS: Implement crankshaft support for nested object literals. 
Port r10061 (c648e1d1)

Original commit message:
This generates optimized code for deep-copying of nested object literal
boilerplates which are statically known. Most of the boilerplates have
already been generated at crankshaft time, so this optimization should
kick in for virtually every object literal. Only nested object literal
graphs up to a certain depth and containing up to a certain total number
of properties are considered for this optimization. This will prevent
explosion of code size due to large object literals (e.g. eval on JSON).
Improves splay performance because object literals are created often.

4ca20a1d35 Simplify stack check instruction in Crankshaft. 
So far we had two types of stack checks: one used for function entries
and one used at loop back edges which uses a deferred code object to
avoid spilling of registers in the loop.

After refactoring lazy deoptimization the first stack check can also
use deferred code. This change removes the first type of stack check
instruction in Crankshaft and uses a deferred stack check in all
places.
