The parser now generates a ConstructorWithTypeArguments error and a new
handleInvalidTypeArguments event after a begin/endTypeArguments event pair
when those type arguments are in a syntatically invalid location.
For example: `new C.n<int>();` in
```
class C<T> { T f; C.n() {} }
main() { var x = new C.n<int>(); }
Most listeners handle this event by dropping the invalid type arguments,
but AstBuilder now preserves those invalid type arguments in the AST
to support better code quick-fixes/quick-assists/refactoring.

The CL is reverted because it didn't account for the case when a check
of a user-specified type argument against the bound depends on another
type that is only known after type inference is done.

The implementation strategy is to replace int literals with double
literals during type inference, provided they occur in a double
context and can be represented exactly as a double. This requires us
to keep integer literals larger than the 64-bit range until after type
inference and to keep the source text of 64-bit integers until after
type inference for error reporting.
We postpone the check for web int literals as well because the
expression generator that was performing it isn't otherwise needed.

* Ensure that we have a .dill file and it has the correct version before
we start decoding it in dump.dart.
* Throw errors, not strings. Ensure that they have a useful
toString().
* Do not print usage except when the command is invoked
incorrectly (wrong number of arguments). Once we get into the
command it's less likely that it's been invoked incorrectly and more
likely that something else has gone wrong.
Because these utilities are invoked from other scripts (like the
fasta command), printing their usage for problems other than
invoking them correctly doesn't match the way that they were invoked
and it's confusing.

This updates the fasta parser to use the "incorrect" keyword
when "extend" or "on" is used instead of "extends" in a class declaration and
when "extend" or "extends" is used instead of "on" in a mixin declaration.

The code in class_hierarchy.dart that looped over override pairs
included implementations inherited from its superclass as potential
overriders, presumably in a broken attempt to include some interface
checks into the mix.
With this problem fixed, the special case in kernel_class_builder.dart
that excluded overriders not declared in the current class (i.e.
declared in a mixin) could be removed without incurring false
positives.
These override checks performed on members from a mixin produce an
extra context message indicating the class where the two members meet,
giving rise to the override relation (similarly to interface checks).
Since the same member can now override more than one member (or even
the same member more than once), the diagnostics message duplication
check has been extended to also include the context in the comparison.

When a member in the interface of a non-abstract class is found to
have an implementation with the correct name which does not override
the representative declaration of the member in the interface (and thus
has not been checked against that member for override validity), call
the override check to check interface validity.
Override relations thus checked produce an extra context message
explaining that the override relation must hold because both members
are inherited by a non-abstract class.

Also, convert package:vm to use onDiagnostic.
We're consolidating all dependencies on package:front_end in one file per tool.
The idea is, if you want to depend on something in the package:front_end, you modify pkg/front_end/lib/src/api_unstable/vm.dart and consult with the front-end team.
These consolidated files will help us when designing a public API in the future.
