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.

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")

throw either). Fixing this is a separate issue, though (and one that doesn't

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.

Prepare DefinePropertyAccessor for callback transitions.
Although things are currently OK here, in the future it won't be enough to check
for the existence of a CALLBACKS result, we must additionally check that it
actually contains an accessor. In a nutshell: 'sed s/IsFound/IsProperty/' once
again...
Additionally, the control flow in DefinePropertyAccessor has been simplified by
using a helper function.

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

MIPS: Ensure proper alignment of LazyInstance objects.
The template system converts the actual struct type to an array of chars.
Make sure the alignment is kept by the compiler.
This fixes a lot of serialization-related HW tests, for example cctest test-serialize/Serialize.
