When reducing the type promotion in case of assignment, the target
info wasn't correctly handling the reduction to the trivial state.
This caused an error in a following join computation.

Remove HInstructions related to old rti.
Some methods are still called 'fooNewRti'. These will be renamed 'foo'
at the very end of removing old rti.

The biggest impact is removing the orphaned HInterceptors for all the
call instructions lowered to other instructions. (The SSA is much
easier to read with this noise immediately removed!)
I have seen no code differences except one or two pieces of dead code
like `[];` that must have become dead on the last simplify pass after
the last DCE pass.
I am experimenting in another CL with some algebraic rewrites and
simplification of bit operations to target some weak code. This change
makes the rewrites work much better.

A HParameterValue can be an SSA value or a mutable local variable
accessed via HLocalFet/HLocalSet. The latter happens in code that is not
completely SSA-converted (due to exception control flow).
The main bug is that the check on a mutable-variable-mode HParameterValue
should have been on a HLocalGet of the value, and not the HParameterValue
itself. This means that a reference to the HParameterValue cannot be
replaced with a strengthening check, as that breaks the invariant that
HLocalGet/Set refer to variables. There was code in types_propagation
that tried to work around this broken invariant.
The bug (issue 42189) required
- An elided instance method parameter
- try(-catch)(-finally) to avoid complete SSA-conversion
- -O0 to avoid optimizing away the check early with inferred types
The first attempt at a fix was to not check the elided parameter at all
since the default value is statically checked. This is still worthwhile.

Conceptually, this makes sense because a type is not intrinsically top
or bottom or raw, but only in the context of a type system. This also
makes these predicates much more maintainable and puts them in a form
identical to the one at the RTI level.

We were passing arguments as just a `Map` and forcing the Message to
handle the String conversion, but the caller is much better equipped to
do it and prevents the dynamic typing.

This is a temporary workaround. The `dart:html` library contains type
annotations based on the chrome IDL, but it doesn't consider browser
compatibility or whether an API is only supported on some contexts.
We can revert this as soon as `dart:html` is sound again.
See https://github.com/dart-lang/sdk/issues/41960 for details.

Use the collector to distribute lazy statics to OutputUnits. This is
much faster than filtering the lazy statics for each OutputUnit.

ImportSets do not need to store the list of members of the set as it
is available implicitly on the canonical construction path. All that
is required is a back-pointer to traverse the canonical path from the
end (i.e. ImportSet).
This reduces the memory required by DeferredLoadTask by O(N).

For some types it makes sense to distinguish between nullability as a
property of including null and the declared nullability, such as for
type-parameter types and FutureOr types. This CL introduces the
separation between the two concepts. The plan is to use that when
implementing FutureOrType.

- Fix unwrapException to ensure it never returns null.
- Wrap `null` (from JavaScript) if necessary.
- Move `saveStackTrace` to top-level function to avoid closure allocation
- Force inferrer type for unwrapException to non-null to avoid tests
at 'on Object' clauses.
