Try aligning unboxed double array backing store in allocation or scavenge promotion.

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.

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).

MIPS: Improve performance of keyed loads/stores which have a HeapNumber index.

Port r11282 (bd2ab07).

Patch by Daniel Kalmar.

Original commit message:

Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.

For example:

a[-0] === a[0] or

a[0.25 * 4] === a[1]

This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.

As a result the frame rate on the reported benchmark improves by roughly 2x.

This change allows hydrogen instructions to keep track of instructions
that dominate certain side-effects (GVN flags) in the hydrogen graph. We
use the GVN pass to keep track of side-effects because accurate flags

It also adds a new side-effect (kChangesNewSpacePromotion) indicating
whether an instruction can cause a GC and have objects be promoted to
old-space. An object allocated in new-space is sure to stay on paths not
having said side-effect.

Fix WeakMap processing for evacuation candidates.

This fixes processing of WeakMaps so that value entries on an evacuation
candidate are correctly recorded in the slots buffer. We didn't pass the
correct slot into the backing hashtable while visiting values.

Also the live bytes counter for large object space pages was not reset
correctly when incremental marking is aborted.

I'd like to add addr field into EntryInfo struct.
This will give us the ability to keep entries_ list sorted by id.
And based on that fact we will be able to use it for:
1) GetNodeById method and drop sorted version of entries list in HeapSnapshot;
2) building heap stats;
3) doing the fill stage instead of second iteration over heap.

MIPS: Remove static initializers in v8.

Port r11010 (1daa81bc).

MIPS-specific changes:
-register codes and registers are defined using a macro to avoid redundancy
-renamed s8_fp to fp, removed the "fp" alias
-removed kSavedValueRegister (found by check-static-initializers.sh)

Original commit message:

Landing for pliard@chromium.org: Remove static initializers in v8.

This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances a

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/

2. http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This

This CL also modifies the presubmit script to check the number of static initializers.
