In Kernel's TargetFlags, this flag still defaulted to false. Flip the
default to true and update all client code in the SDK. The
expectation is that many of the places that now pass false explicitly
really just want the default, but that will be verified separately and
then the flag will be removed.

Entry points JSON files are deprecated (replaced with pragmas).
So TFA should not require them. As a sanity check, it will complain
if an entry points JSON file is not empty.

This is required for tracking type arguments, since field initializers can
reference type variables from the enclosing class.
Also a few drive-by spelling fixes.

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.

This CL adds auto-generation of entry points JSON file for standalone VM
during build (in runtime_kernel target, as it is only used for
kernel-based transformation).
pkg/vm/tool/precompiler2 script is changed to automatically pass
auto-generated entry points to gen_kernel.
New option --entry-points is added to pkg/vm/bin/gen_kernel.dart in order to
specify custom entry points files.
Checked-in entry_points.json is still used for testing and in gen_kernel
if --entry-points is not specified.

This CL changes incoming argument types of raw (opaque, untracked) calls
in type flow analysis (TFA) from static parameter types to 'dynamic'.
Currently, raw calls are used to approximate calls from native code to
entry points and calls through tear-offs. Using static parameter types
is not correct for raw calls as incoming argument types should not include
the effect of strong mode argument type checks inside the body of a
method. This change has almost no impact on the results of analysis
because intersection with static parameter types is already performed when
applying a summary.
To fill out the remaining gap, static types of fields are now taken
into account in TFA: type of an incoming value is intersected with a static
field type in _FieldValue.setValue().
Also, this CL includes a fix for handling cyclic type parameters in TFA
(this problem appears on language_2/cyclic_type_variable_test test as
soon as TFA starts looking at static types of fields).

This CL revises implementation of concrete types and set types in
global type flow analysis. For concrete types, unique comparable
class identifiers are assigned. SetType, instead of storing elements
in a Set, stores them in a List ordered by class identifiers.
This makes comparison, union and intersection of set types linear of
number of elements.

* Invocation handlers and InvocationAnalyzer are revised to reduce
complexity of the code, improve precision and efficiency of analysis.
* Invocation now has 2 subclasses: DirectInvocation and
DispatchableInvocation; processing of invocations is moved to these
subclasses and simplified.
DirectInvocation is responsible for processing particular
methods and fields, while DispatchableInvocation processes polymorphic
calls by collecting targets and accurate receiver types for each target,
and delegating to DirectInvocations for processing of each target.
* Dynamic tear-offs and dynamic calls via getter/field are
supported.
* Invalidation of field initializers is implemented.
* Implicit 'return null' at the end of a function is correctly
detected.
