99e0908cfd Cleanup Runtime_SetCode and drop EnsureCompiled. 
This change triggers compilation for a given closure instead of the
shared function info. It will allow for even more cases to be compiled
lazily.

98db16d94f Progress towards making Zones independent of Isolates and Threads. 
This CL changes some parts of the code to explicitly pass around a
Zone.  Not passing in a zone is okay too (in fact most of v8 still
doesn't), but that may incur a TLS lookup.

3d45e98b5e Remove %_SwapElements. This inlined runtime contained an optimization that was dangerous in the presence of incremental compaction. It also prevented QuickSort from array.js from being optimized by Crankshaft, so it is probably better to do without it. We have high hopes that this will fix bug=117879.

292e007cf3 Remove more assumptions from debug tests. Even though a function 
is optimized, does not mean all frames on the stack are optimized.
Also, when we ask for the list of scripts we may get more or less
depending on GC timing.  Also fixed a presubmit error and made
%GetOptimizationStatus a little more honest.

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.

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).

43a52c4cee Refactoring of code generation for declarations, in preparation for modules. 
Do proper dispatch on declaration type instead of mingling together
different code generation paths. Once we add more declaration forms,
this is more scalable.

In separate steps, I'd like to (1) clean up the logic for DeclareGlobal,
and (2) try to reduce the special handling of the name function var if
possible.

4cb600962f Make setting of accessors even more atomic. 
Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.

While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

1729e3c0dd Make the runtime entry for setting/changing accessors "atomic". 
Previously, there were 1 or 2 calls to the runtime when accessors were changed
or set. This doesn't really work well with property attributes, leading to some
hacks and complicates things even further when trying to share maps in presence
of accessors. Therefore, the runtime entry now takes the full triple (getter,
setter, attributes), where the getter and/or the setter can be null in case they
shouldn't be changed.

For now, we do basically the same on the native side as we did before on the
JavaScript side, but this will change in future CLs, the current CL is already
large enough.

Note that object literals with a getter and a setter for the same property still
do 2 calls, but this is a little bit more tricky to fix and will be handled in a
separate CL.

371ed3e974 Use an enum for indicating the component of an AccessorPair instead of a boolean flag. 
In addition, this CL introduces a tiny new helper, which will come in handy later,
plus some minor cleanup.
