VM treats instantiated function types with NumParentTypeArguments() != 0
as non-instantiated (as they potentially depend on the numbering of
enclosing type parameters) and would explicitly instantiate such types.
So bytecode generator needs to make sure that instantiated types,
instantiated type arguments and types used in constants always have
NumParentTypeArguments() == 0, so they would not need unnecessary
instantiation.

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.
