Bytecode generator needs to know the runtime semantics of Dart types,
but TypeEnvironment.isTop predicate does not use erasure of extension
types and does not return true for extension types based on other top
types (e.g. dynamic).

When creating function types, VM takes number of parent function type
arguments into account. So function types with distinct number of
parent function type arguments should not be merged in the bytecode
object table and should be represented as distinct types.

to initialize closure entry point.
* Fix null handling in operator== to be before argument type checks.

Add dart2bytecode tool which takes Dart sources and produces
Dart bytecode. The tool uses common front-end (CFE) to parse Dart
source code and contains bytecode generator which translates
kernel AST to bytecode.
