- appJit has been replaced by appJitk and is no longer.
- precompiled has been replaced by dartkp and is no longer used.
- For the precompiled runtime, default to dartkp.
- Remove status file references to these compiler options and normalize
status files.

Also fix the type inference algorithm so that when it explores
multiple alternatives (as a result of the use of FutureOr<>), if one
alternative generated some constraints but failed to produce a match,
it rewinds those constraints and tries the other alternative.
(Previously, it erroneously assumed that if any constraints were
generated, the alternative matched successfully).
Also add unit tests to verify the proper operation of the subtype

As tests/language_2/tearoff_dynamic_test.dart shows, it is perfectly
valid to take a tear-off of an instance method from null, and then call
hashCode from such tear-off.
The implementation of hashCode for closures, Closure::ComputeHash()
was calling Instance::Cast(receiver) which asserts for null.
This code is revised to allow null receiver.

This should be safe since the purpose of the inference is to find an
exact match for each type parameter; if an exact match is found but it
doesn't satisfy the "extends" constraint, that will be detected and
reported later. If an exact match isn't found, the type bound will be
filled in my instantiate-to-bounds.

Original description:
Change front_end handling of callable classes.
This CL is the first in a series of CLs to change the handling of
callable classes in Dart 2.0.
For purposes of this description, a "callable class" is a class whose
interface contains a `.call` method.
In Dart 1.0, a callable class was considered to be a subtype of the
`.call` method's function type. This allowed the user to create
custom objects with similar behavior to closures, but with additional
fields and methods.
In Dart 2.0, a callable class is just an ordinary class, with no
subtype relation to any particular function type. (Note however that
it is still permissible for a class to declare that it "implements
Function").
To reduce the amount of code broken by this change, a piece of
syntactic sugar is being added: if an expression whose static type is
a callable class appears where a function type is expected, an
implicit tear-off of the `.call` method is inserted.
Note that it is still possible at compile time to invoke an expression
whose static type is a callable class, and it is still possible at
runtime to invoke an expression whose runtime type is a callable
class; in both cases, this is considered an implicit invocation of the
class's `.call` method. This is unchanged from Dart 1.0 behavior.
This CL introduces test cases for the new behavior, and implements the
implicit tear-off of `.call` in the front end.
Still to be implemented in future CLs:
- Spec text needs to be written.
- DDC/analyzer code needs to be written to perform implicit tear-offs
of `.call`.
- The subtyping algorithm in DDC, analyzer, VM, and dart2js needs to
be changed so that callable classes are no longer considered
subtypes of any particular function type.
- A small corner case involving type parameters still needs to be
addressed (see TODO in
pkg/front_end/lib/src/fasta/type_inference/type_inferrer.dart).
Fixes#32064.

If an implicitly typed top level variable or field depends on an
implicitly typed instance getter or instance field, the analyzer
implementation of type inference isn't guaranteed to infer the
depended-upon field first, therefore the type might be inferred
incorrectly.
The new front end doesn't have this problem, so the user's code will
execute correctly at runtime, but they might get confusing results
from the analyzer. To alert users of this problem, we issue a
compile-time warning whenever an implicitly typed top level variable
or field depends on an implicitly typed instance getter or instance
field.

The optimizer uses the "is more specific than" relation to eliminate type tests.
In strong mode, the "is more specific than" relation is supposed to be identical
to the "is subtype of" relation. However, it is not quite true, and this is the
cause of this bug. In non-strong mode (Dart 1), the "is more specific than"
relation uses covariance for both result type and parameter types of functions.
In strong mode, we need covariance of result type and contravariance of
parameter types.
Added regression test and updated status files.

Note that none of the back-ends handle Instantiation nodes yet, so the
language_2 tests added in this CL
(instantiate_tearoff_after_contravariance_check_test,
instantiate_tearoff_of_call_test, and instantiate_tearoff_test) fail
pretty much across the board right now.
Includes two fixes to Instantiation.getStaticType and the kernel type checker:
- Previously, they attempted to perform substitution on the full
function type, which had no effect because the type parameters were
bound.
- The type checker was not checking that type parameter bounds were
satisfied.
Note that the front end doesn't yet check that type parameter bounds
are satisfied by the inferred type parameters. I will address that in
a follow-up CL.

The analyzer used to emit a warning when a type parameter to a generic
method was used in an "is" check. This warning was there to help
users write code that worked correctly on both Dart 1.0 and 2.0. Now
that 2.0 generic methods are being more broadly supported and used,
this warning is blocking further library work, and is being removed.

Without strong mode, a "good enough" implementation is to simply call
the generic method with "dynamic" for the type arguments, which is what
this does. That should be enough to unblock our internal users.
We also need to not report a compile error when
dart_internal/extract_type_arguments.dart imports the hidden
"dart:_internal" library.
This patch does both of those for the VM and dart2js (using its old
front end).
Note that the test still fails because the test is more particular than
most actual user code would be -- it validates that the instantiated
type arguments are *exactly* correct, and not that the returned object
is merely subtype compatible.
