Preliminary testing shows, this increases performance by around 20%. The
main benefit is by re-using a warmed-up VM and not start one from
scratch for every compilation.
Going forward we can do more optimizations, e.g. reading the platform
dill file only once into memory (instead of repeatedly) ...
=> This requires us using the new state-full IKG compiler.

The informal spec for strong mode top level inference
(https://github.com/dart-lang/sdk/pull/28218) says "If there are
multiple overridden/implemented methods, and any two of them have
non-equal types (declared or inferred) for a parameter position which
is being inferred for the overriding method, it is an error."
This CL fixes several SDK errors that arise from this rule. For
example, the classes _Closure, Function, and Object contained members
declared as follows:
class _Closure implements Function {
bool operator ==(other) ...
}
class Function {
bool operator ==(Object other) ...
}
class Object {
bool operator ==(other) ...
}
The type of Object's operator == was (dynamic) -> bool; the type of
Function's operator == was (Object) -> bool; therefore the type of
_Closure's operator == (which overrides both, since _Closure extends
Object and implements Function) cannot be inferred and must be
specified.
A similar situation exists for _Double and _IntegerImplementation
(both implement num, which declares operator == to have type (Object)
-> bool), and _Uri (which implements Uri, which declares operator ==
to have type (Object) -> bool).
This CL fixes the error by specifying the type explicitly in the
classes _Closure, _Double, _IntegerImplementation, and _Uri.

When the body of a function node in a Procedure is lazy loaded the value
of the Procedures transformerFlags is not properly set before the body
has been read. That means that one can get the wrong result.
This CL makes sure to read the body (thereby setting the correct result)
before answering. The same thing is neccessary when setting the value to
avoid it being overwritten later.

There is no actual implementation here yet (that's your job :) ), but there is:
- An external method in dart:_internal, extractTypeArguments().
- Empty patch methods for that for the VM, dart2js, and DDC. These need to have implementations
filled in.
- A "dart_internal" package to expose a subset of the API. It gives you:
extractListTypeArgument()
extractMapTypeArguments()
We'll bring this into Google, but not publish it externally unless we find we really need to.
- A test for the behavior. It probably has bugs since I can't run it.

UnboxInteger32Instr, UnboxUint32Instr, UnboxInt32Instr and UnboxInt64Instr)

The non-speculative mode is used when generating double and int64 operations

Also, this CL disables couple of cases in --experimental-strong-mode which
do not work yet. This is a preparation for turning --experimental-strong-mode
