This preserves the invariant that method invocations and property sets
with an interface target handle static types at the call site.
This is a prerequisite to improving dart2js with implicit checks.
With this we can mark dynamic invocations a statically safe and
discover when instance methods don't need to check parameter types.

This uses the information from the static types now used in inference which
can improve the precision in particular for generic classes. Since type
masks lose the type argument information, we cannot expect locating members
based on the type mask to be more precise than what has been found through
the static types.
This CL also expands the unit test framework to support unit test of
optimizations and the emission model, including tests of the improved
field access handling.

This normalizes all accesses of Object properties on dynamic receivers
to target the corresponding Object members.
CFE already set the interface target on for instance `a == b` where `a`
has static type `dynamic` but didn't for the implicit call to `==` in
for instance `a?.b`.

This speeds up the computation of static type by avoiding repeated
visits of subtrees. The change also paves the way for improving
static type computation beyond what is specified. For instance by
handling negative type promotions.

This includes the unknown potential targets of access to js-interop
members. Since we don't know actual classes implementing the js-interop
classes we just assume it could be any of them.

* The J model is in the /js_model/ folder and KernelToElementMapForBuilding is renamed
to JsToElementMap.
* The K model is in the /kernel/ folder and KernelToElementMapForImpact is renamed
to KernelToElementMap.
* Code shared between JsToElementMap and KernelToElementMap is in the /ir/ folder using
the interface IrToElementMap internally.
* KernelToElementMap and JsToElementMap do _not_ implement IrToElementMap so all code
that is not part of the implementation must explicitly use one or the other.
* Both KernelToElementMap and JsToElementMap extend KernelToElementMapBase
but this will be changed in a follow-up.
