cac8bbff6e Replaced the --limit-inling flag by three separate flags and bumped hard limits. 
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
bit for more consistency.

3760893edd Fix bug in forced-deletion of globals. 
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.

7d22d73ebf 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.

977b602727 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.

Previously it was owned by pointer but now it is not necessary and we can own it by value.

47d07b8a7b 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.

174967d867 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.

6a1b70ccbc Regexp: Unify the lookahead code for the BoyerMoore-like skipping 
and the lookahead code for simplifying \b.  Also cache lookahead
results on the nodes, fix a memory leak and remove some character
class code we are no longer using.
