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.

asiva@google.com 5fd180cdfc 1. Register canonical names for internal VM classes and get rid of the method GetSingletonClassName 
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.
    (as a follow up change I will consider completely removing functions cache)

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).

Issue 3551

This change adds const as a valid keyword to declare fields and
variables. The mandatory initializer has to be a compile time
const expression.

Static final variables still have to be initialized with
compile time constant expressions. I will add non-const static
finals (issue 3558) in another change.

Other small changes:
- allow null in some compile time constant expressions.
- allow only numbers, booleans, strings and null in compile time
  constant string interpolation.
