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.

MIPS: Implement rudimentary module linking.
...
Port r11336 (6dd4e844)
Original commit message:
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.

Fix fast array literals to ignore prototype chain.
...
This makes sure that boilerplate objects for array literals with
non-constant elements (which will contain the hole at non-constant
positions) will not cause prototype chain lookups when generating
optimized code.

Fix a bug in heap profile tracing of closures.
...
The heap profile tracers assumed that a closure always closed over a
function context. This is obviously not true (e.g., function expressions
nested inside catch or with). This assumption could lead to using a
function's scope info to interpret a catch or with context.
