The fasta parser sometimes "drops" unexpected tokens during recovery.
When this happens, the dropped or skipped token is not reported to
the listeners, and thus does not become part of the analyzer's AST.
These tokens are still in the token stream, but will not be found
by the existing CompletionTarget mechanism.
For example, the fasta parser parses
'if (v i) {}' as 'if (v) {}' and drops the 'i' token.
This CL introduces a new CompletionTarget.droppedToken field.
If a keyword or identifier has been dropped by the parser,
but overlaps the code completion offset, then that token
is placed into this new field.
In the example above, when code completing the 'i',
the CompletionTarget will now be
containingNode = '(v)'
entity = ')'
droppedToken = 'i'
