When `-fdebug-dump-symbols` is supplied with `-funparse`, include symbol
information in comments in the Fortran output. This will be used for
testing to verify that correct symbols are defined and references in
the right place.
In `UnparseWithSymbols()`, walk the parse tree and collect symbol
definitions and references, organized by statement. When a symbol is
defined across several statement it is associated with the first.
The definition of implicitly defined symbols is associated with the
first reference.
To write out the symbol information, a new optional argument is added to
`Unparse()`: it is a function that is called immediately before each
statement is unparsed. We pass in a function that prints out the symbol
information collected for that statement.
Add `Symbol::GetType()` to make it easier to write the symbol types
and add `Symbol::SetType()` for uniformity.

Unparse takes a parse tree and converts it back to Fortran.
class UnparseVisitor implements a parse tree visitor that emits
the appropriate Fortran source for each node that it visits.
It is only partially implemented so far.
Change f18 to dump the parse tree using Unparse.
