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.

Avoid sharing AccessorPairs during Genesis.
...
To test the upcoming changes for map sharing in the presence of accessors, it is
essential that we keep a few global invariants: The map tree should always stay
a tree and AccessorPairs should not be shared between different DescriptorArrays
and/or StringDictionaries. This CL adds a test method for the latter invariant
and makes some changes to the bootstrapping process to avoid such sharing.
Note that we can't enable the new test method permanently yet, because we
currently go back and forth between fast mode and slow mode when adding an
accessor and break this invariant temporarily. This will be handled in a
separate CL.

3. heap.h has inline functions functions defined that call

Randomize the seed used for string hashing. This helps guard against
...

Reland 10216 - Optimize the equality check case of ICCompare stubs.
...
Now with arm and x64 support. Additionally, added default unreachable case to switch statement in CompareIC::TargetState to make win and mac compilers happy.
Reviewer guide:
This is an exact copy of 10216 except:
src/arm/*
src/x64/*
src/ic.cc (added default case to swith in CompareIC::TargetState)
