3515559a38 Increase old space in cctest/test-api/HugeConsStringOutOfMemory test. 
This test is failing on MIPS since r11715 (a7d6f92c),
it seems that after the modifications in bootstrapper.cc,
this test runs out of old generation space on MIPS.

19ece2bec8 Enable lazy compilation for non-trivial outer contexts. 
This changes the compiler to be more aggressive about lazy compilation
of closures with non-trivial outer context. Compilation can only be
triggered with a valid outer context now. One exception is the debugger,
which can request compilation of arbitrary shared code, but it ensures
to trigger compilation only at points where no context is needed.

31a0d0257c Serialize edge counts instead of indexes in heap snapshot. 
The serialized node structure currently holds an index
of its first containment edge in the edges array.
The index can be quite big (up to 7 digits for large snapshots).
The patch changes the serialization format to pass
node containment edge count instead. For most nodes the count
is just a single digit number.
This reduces serialized snapshot size and therefore its transfer time.

e4c472a7af Implement correct checking for inherited readonliness on assignment. 
Removes 6 out of 8 of our remaining unintentional failures on test262.

Also fixes treatment of inherited setters added after the fact.

Specifically:

- In the runtime, when looking for setter callbacks in the prototype chain,
  also look for read-only properties. If one is found, reject (exception in
  strict mode). If a proxy is found, invoke proper trap.
  Note: this folds in the CanPut function from the spec and avoids an extra
  lookup over the prototype chain.

- In generated code for stores, insert a test for the maps from the prototype
  chain, but only up to the object where the property already exists (which
  may be the object itself).
  In Hydrogen, if the found property is read-only or not cacheable (e.g. a
  proxy), bail out; in a stub, generate an unconditional miss (to get an
  exception in strict mode).

- Add test cases and adapt existing test expectations.

Reverting because the dict-mode to fast case transformation loses the iteration order information.

ff216c9cea Re-land: Use map transitions when defining accessor properties. 
This is basically r11496, with the following changes:

 * Set back pointers in maps (cherry-picked from r11528)

 * Fixed size calculation in CopyInsert, as proposed by mstarzinger/rossberg

 * DefineFastAccessor uses GetCallbackObject instead of GetValue (for __proto__)

 * Put the code under a new flag, which is disabled by default

 * Cut down the corresponding regression test

 * Adapted bootup memory test, we actually only need a bit more memory on 64bit without snapshots, which can easily explained by more live maps lying around. Note that the snapshot variants are back to their previous limits.

Next steps: Investigate any performance degradationswith the flag enabled, and finally remove the flag when things are OK. Furthermore, GetCallbackObject should be merged into GetValue, the distinction is confusing and error-prone.

065cc14449 Use map transitions when defining accessor properties. 
AccessorPairs can now contain map transitions, which is similar to our current
handling of CONSTANT_FUNCTION/CONSTANT_TRANSITION, but generalized to a pair for
holding info about the getter and the setter. This way we can achieve map
sharing for objects with accessor properties, which is a prerequisite for making
them fast via inlining. We fall back to the previous way of handling accessor
properties when sharing is not possible or we don't handle a special case.

Note: When an exisiting accessor property is redefined we could in principle
move the AccessorPair out of the descriptor into the object itself (again just
like the way we do something similar for CONSTANT_FUNCTION/CONSTANT_TRANSITION),
but this would require a new property kind for holding a pair of values. Perhaps
we can implement this later, but for now this hopefully rare case is handled
like before, losing map sharing and potentially creating more maps than strictly
necessary.

93113da5a2 Eliminate redundant array bound checks (checks already performed earlier in the DT). 
As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.

7d22d73ebf Fix issues when stressing compaction with WeakMaps. 
1) While marking the backing hash table of a WeakMap we also need to
   record the slot because it might be on an evacuation candidate.
2) With incremental marking one backing hash table might be marked more
   than once because the WeakMap might have gone through a white to gray
   transition.
3) The corner case when the allocation of the backing hash table itself
   causes a GC, leads to a WeakMap with an undefined table field, so we
   still need to handle this case correctly.

ab26fb6b21 Implement rudimentary module linking. 
Constructs the (generally cyclic) graph of module instance objects
and populates their exports. Any exports other than nested modules
are currently set to 'undefined' (but already present as properties).

Details:
- Added new type JSModule for instance objects: a JSObject carrying a context.
- Statically allocate instance objects for all module literals (in parser 8-}).
- Extend interfaces to record and unify concrete instance objects,
  and to support iteration over members.
- Introduce new runtime function for pushing module contexts.
- Generate code for allocating, initializing, and setting module contexts,
  and for populating instance objects from module literals.
  Currently, all non-module exports are still initialized with 'undefined'.
- Module aliases are resolved statically, so no special code is required.
- Make sure that code containing module constructs is never optimized
  (macrofy AST node construction flag setting while we're at it).
- Add test case checking linkage.

f4c15c4ec2 External references should not affect dominance relation. 
Separate objects into two groups: reachable from a window (user),
and unreachable (system). Then do not take into account links
that come from system group to the user group when calculating
dominance relation.

62945585fd Implement ES5 erratum: global declarations shadow inherited properties. 
I also discovered that our treatment of const declarations is inconsistent
when inside a global eval under 'with' (i.e., when created by
DeclareContextSlots). That is,

  var x;
  eval("const x = 9")

and

  var x;
  eval("with({}) const x = 9")

differ (the former assigns 9, the latter throws). This appears to be an
oversight from earlier changes to our const semantics (the latter shouldn't
throw either). Fixing this is a separate issue, though (and one that doesn't
seem quite worthwhile).

17632e447c Add size metric into Heap Stats. 
The stats data have only count field at the moment.
A constantly growing array of integers also can be a reason of a leak.
Ans we have to have a way to detect such kind of leaks.

Drive by fix:
FindObject and AddEntry were replaced with FindEntry/FindOrAddEntry pair.
