Instead of just giving up try to give as much information as possible
including error code, error returned by Dart_StringFromUtf8 and
ascii portion of the OS error message.
We are making this change because we are getting reports of
ProcessException being thrown with "OS error message was a
not a utf8 string." message. There is no way to reproduce
these situations so instead we are going to add additional
information into the fallback message to aid the investigation.
TEST=tested manually by simulating fallback to the newly added code

* Correctly handle _Smi type when producing TTS for it.
Previously it would not correctly establish that an instance
of _Smi is assignable to _Smi causing it to always fall through
into runtime system;
* Correctly handle Null type as a type argument when checking C<Null>
is C<X>, if Null is assignable to X we need to explicitly check if
type argument is Null because cid ranges don't really handle this
check.
* Strengthen the assert checking that TTS specialization succeeded:
check that specialization is (bitwise) different from the previous
version of the stub. If they are equal that means specialization
failed.

The single-entry / single-exit patterns of the CFG prevent inlined
throw statements and throw expressions from having exit edges like a
statement-level throw. If the join block is not reachable on one path
of a diamond, the kills on the infeasible path can be ignored in the
join.

The type of the `onError` parameter of Future<T>.catchError is just Function,
but the function can either have signature `FutureOr<T> Function(dynamic)` or
`FutureOr<T> Function(dynamic, StackTrace)`. This change adds checks for return
statements in a function literal passed to `onError`, and the return type of a
function-typed expression passed to `onError`.
We still need to check parameter types.

The analyzer has not been migrated, so this is based on manual
inspecation of the API about what can be `null` for now.
Note with the analyzer from master (running in nnbd by default) this
file contains many nullable to non-null assignments. However, we cannot
migrate this file to nnbd yet because of the language version it's used
in.

From the times where some of the type arguments should have been
reported as warnings, the procedure was run twice in two different
modes, in order to report some issues as errors and some as warnings.
This CL is a cleanup that invokes the procedure once. Additionally, a
refactoring of the return value discipline is made: it always returns
a list and never returns null. An empty list is returned if there are
no issues.
