To enable bytecode generation, toggle kEnableKernelBytecode flag at
the beginning of pkg/vm/lib/bytecode/gen_bytecode.dart.
This will also enable generation of bytecode in platform dill files.
Also, bytecode generation can be enabled using --gen-bytecode option of
pkg/vm/tool/gen_kernel.
In kernel binaries, the generated bytecode and constant pool are
placed into 'vm.bytecode' metadata attached to members.
pkg/vm/tool/dump_kernel tool can be used to disassemble
bytecode and print constant pool.
Differences between generated bytecode and original DBC are
described in pkg/vm/lib/bytecode/dbc.dart.
Format of constant pool is described in
pkg/vm/lib/bytecode/constant_pool.dart.
Currently, only a small subset of Dart language is supported.
Bytecode generator will not emit vm.bytecode metadata for a
member if its body has an unsupported operation.

When recovering from an invalid annotation in a type variable
(e.g. "< @Foo.bar T >"), the parser could get stuck in an
infinite loop trying to recover. This fixes that situation.

The values returned from calling sync*, async and async* are now parameterised.
Simple cases where the type has no type parameters are handled.
The next step is to introduce a signature-like j-model entity to compute the type in more complex cases.

One thing to be careful of here is that function type bounds may be
left unbounded. However, their parameters and return type cannot refer
to a type parameter for resolve-to-bounds to work.
There are also a large number of ways that this can loop infinitely, and
a number of new guards had to be added (as well as some test cases) to
catch them all.

This improves recovery when parsing conditional import expressions
by repositioning the synthetic closing ')' that was inserted by the
scanner in a less than optimal location.
This approach relies on the beforeSynthetic field being set correctly.
While the scanner still sets the 'next' and 'beforeSynthetic' fields
directly for efficiency, most other functions which update an existing
token stream have been revised to call 'setNext()' rather than setting
the 'next' field directly. This ensures that the 'beforeSynthetic' field
will be correctly updated.

This CL updates SyntheticToken to have a new beforeSynthetic field
and the fasta scanner to set that field for synthetic ")", "]", and "}" tokens.
This makes it much more efficient for the parser to move a synthetic
closer when the scanner has inserted it in a less than optimal location
in the token stream.

Make all lists returned by ast_from_binary growable so the ast is more consistent with the ast generated by parsing dart code which generally contains growable lists as opposed to fixed-length lists.
This fixes a bug in the Flutter --track-widget-creation transform
where it would fail on an AST if it was deserialized from a binary file
rather than parsed from source code.

This CL improves recovery given invalid or malformed formal parameter

improving recovery when parsing field initializers, and in the process,
further reducing the size of parseType and eliminating 6 unused
TypeContinuation elements.

Our generated code does not keep the context in a special register
anymore (for quite some time now). The context is just another definition
in the IR language and gets assigned register locations by the linearscan
register allocator.
Furthermore we no longer use an empty context for closures which have no
captured states, instead the context of those closures is just `null`.
This CL therefore removes Object::empty_context() and the CTX constant.
