Jens Johansen f72603ab45 [fasta] Allow --dump-ir to print error program 
For instance, with the program snippet from issue #31409 one would not
get any other output than the errors, and one would have to explicitly
dump the dill file afterwards to see what was actually generated.

This CL changes this, so the error-library is also printed (in addition
to the, at least in the case of issue #31409, empty list) as in

```
$ pkg/front_end/tool/fasta compile tmp.dart --dump-ir

tmp.dart:2:4: Error: Expected a function body or '=>'.
Try adding {}.
V();
   ^
tmp.dart:3:5: Error: Duplicated definition of 'V'.
var V;
    ^
tmp.dart: Error: Duplicated name: 'V'.
tmp.dart:2:1: Error: Duplicated name: V
V();
^
library;
import self as self;

static method #main() → dynamic {
  throw "tmp.dart:2:1: Error: Duplicated name: V\nV();\n^";
}
```

Front end for Dart

This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.

End-users should use the [dartanalyzer][analyzercli] command-line tool to analyze their Dart code.

Integrators that want to write tools that analyze Dart code should use the [analyzer] package.

Note: The APIs in this package are in an early state; developers should be careful about depending on this package.
