This allows stackmaps with varying lengths in the same function, necessary
for the way we plan to support bitmaps for saved live registers.

hausner@google.com 9dc7ab8e1e Implement import scope 
Implement the new scope rule for imports.

- Imported identifiers are in a scope that is shadowed
  by the importing library's top-level scope.
- Conflicting names imported from different libraries
  are not an error unless the name is referenced.
- Conflicting type names are only an error in checked mode.

In a follow-on change, I'll remove the "imported_into" pointers in libraries. They are no longer needed.

Only allocate space for the bits covered by the stackmap, instead of
for the backing store of the utility class that built it.  Fix a bug
where the size in bytes was multiplied by the word size in bytes.

Also do some cleanup of the stackmap code and renaming in the tests.

cshapiro@google.com 265e2306f5 Add a weak property type to the virtual machine. 
Weak properties are key-value pairs.  The liveness of the key determines
the liveness of the value.  If the key is reachable the value is traced.
However, if the key is unreachable, the value is subject to finalization.

At present, the sole finalization action is clearing the key and value
fields.  However, it is possible to extend this to invoking callbacks or
other techniques, as well as processing values in topological order.

2. Create the empty_array object as a singleton in the VM isolate and remove it from the object store
3. Remove eager population of the functions_cache entry in the class. This results in a pretty impressive reduction of the initial isolate heap size:
    - on IA32 it goes from 1331k to 1071k
    - on X64 it goes from 2431k to 1911k
    - snapshot size also is reduced from 859219 bytes to 789147 bytes.

the terminator.

have a templatized Alloc function:

  zone->Alloc<Type>(len)

This is better for security, as we can check for integer overflow in
the size computation before performing the allocation.  Before, we
often failed to check this.

regis@google.com 12de02cbab Associate the correct type to method receivers (instead of Dynamic type). 
Properly name the first implicit parameter to factories as ':type_arguments'
(instead of 'this', which made it accessible to user code).
Various cleanup.

turnidge@google.com 8b68d343c7 Enforce length/size limits for variable size heap object in order to 
avoid overflow.

For each variable size heap object, compute the maximum number of
elements and use that in the ::New functions to avoid overflow.  If a
bad length/size reaches a ::New function, that is a FATAL error -- the
problem should have been caught earlier by the dart api or by the
library code.

Add "border guards" in the dart api and in library calls which cause
new variable size heap objects to be allocated.  We check for invalid
length/size and throw explanatory error messages.

hausner@google.com b3917271aa Optimize away most implicit const getter functions 
If a static field has a very simple initializer expression
(a literal number or string for example) we initialize the field
directly while compiling instead of generating an implicit
getter. We only do this if the type of the expression is
assignment compatible with the field. If the expression is not
compatible, we let the implicit getter do the error checking.

This eliminates about 330 implicit getters in the core libraries
and saves 35k in the snapshot (830k, down from 865k).

Remove kAbstract from the list of function kinds.  It now has its own

abstract getters and setters.
