This change makes experiments with inlining limits much easier. Note that the
default values for the limits keep their old values for now. Renamed things a

When inling functions across contexts in optimized code and using
ForceDelete from the API to delete a DontDelete global property we
can end up returning the hole value instead of throwing a ReferenceError
as expected after accessing a deleted global variable.

~~ is commonly used to truncate a value to int32 (ToInt32).

This change avoid actually emitting the bitwise operations, and

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.

Previously we got stuck in the int32 state, because this handled everything
without a type transition. Note that other platforms do not have this bug.

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.
