server is started.
When the incremental compiler is used it accumulates state that
increases the footprint of the process. This state is needed only
when the 'reload' or 'expression evaluation' functionality is used
in the debugger.
Currently in the VM we do not have a good way of detecting when the
debugger will be used as the vm service observatory functionality
can be turned on dynamically after the program has started.
This CL turns on the incremental compiler only when command line options
are used to start the observatory server. We could run into issues with
'expression evaluation' when the observatory is started dynamically after
the program is loaded.

The VM debugger expects _completeOnAsyncReturn to be called when
returning from an async function for stepping out of the async function
to work.
This CL does just that.
Note that `_completeOnAsyncReturn` only exists in the VM, but as
the async transformation is only run for the VM target that shouldn't
be a problem.

Bytecode for 'assert' statement includes source positions, which are
different on Linux and Windows due to different newline characters.
This causes bytecode generator tests to fail on Windows, as expected
output includes source positions calculated on Linux.
To avoid these failures, new flag 'omitSourcePositions' is added
to bytecode generator and used in the bytecode generator test.

Argument type checks could use receiver to get instantiator type
arguments. Receiver could be captured and allocated in a context.
So initial context should be allocated before doing argument type
checks.
This CL also removes useless storing of uninitialized (null) context into
'parent' when allocating initial context.

* Argument count corrected when calling generic instance method
(type arguments should be counted in a total arguments count in
InstanceCall1 instruction).
* Argument count corrected in ArgDesc when calling Map._fromLiteral
factory constructor.
* Type parameters of a factory constructor are treated as class type
parameters to ensure that instantiator type arguments are pushed.
This is needed as VM converts type parameters of factory constructors
into the class type parameters (they are distinct in kernel).
* Implicit parameter for passing type arguments to factory constructors
is now handled separately from function type arguments.
It is used as instantiator type arguments for instantiating types.
Unlike function type arguments, this parameter can be captured.

The `@pragma` annotation on `vmservice_io.main` is modified to only mark it as a
root on non-product builds. Since the annotation is evaluated in the constant
transformation, we need to thread a flag through `gen_kernel.dart` indicating
whether the Kernel produced should target a product precompiler.
# Test Plan
Tested locally on Flutter. Unfortunately it's not possible to test the scenario where
`vmservice_io` is not included, since we don't have any "product" bots. Soon the
flag will be introduced into Flutter, and we will have some coverage from there.
