This option allows the completion position to be an offset from the
start of each token, and plays well in each overlay mode. For the
original content:
```dart
void main() {
foo();
}
```
In OVERLAY_NONE mode, completing on `main`, with `--prefix-length=2`,
we complete at:
```dart
void main() {
^
foo();
}
```
In OVERLAY_REMOVE_TOKEN mode, completing on `main`, with
`--prefix-length=2`, we complete at:
```dart
void ma() {
^
foo();
}
In OVERLAY_REMOVE_REST_OF_FILE mode, completing on `main`, with
`--prefix-length=2`, we complete at:
```dart
void ma
^
```

This causes completion failures to be split into two groups: those for
which there was no suggestion and those for which the name was suggested
but the wrong element was selected (as in the case where the correct
element shadows the one that was suggested.
In addition, the both groups of failures are now further grouped by the
location in which they occur.
Finally, failures to complete in hide and show combinators are temporarily
ignored until we can figure out how to complete as if the target identifier
wasn't already in the list.

This should allow doing partial migration, specifically protocol files,
which are imported by other libraries, but are a small library cycle
that does not import much outside of it.
