Fix bug recognizing derived type constructor call

Tim Keith d7d69474c8 [flang] Fix bug recognizing derived type constructor call 
A ProcedureDesignator is a derived type constructor call if the name
resolves to a derived type. We need to recognize it as such and not
report an error. It may be in another derived type so we have to call
FindSymbol() first to find the derived type.

Most of the diffs are due to `symbol` changing from a reference to a
pointer.

In this example we were reporting an error on the first `t1()` and
resolving the second as an external function call.
```
module m
  type :: t1
  end type
  type(t1) :: x = t1()
  type t2
    type(t1) :: y = t1()
  end type
end module
```

The specific procedures in a generic interface must be all functions or
all subroutines. If there is a derived type with the same name they can
only be functions.

Tim Keith 89840b5087 [flang] Support unparse with symbol annotations. 
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.

Tim Keith c7eb38530c [flang] Fix problems in PR 109 when compiling with clang. 
This gets the code base back to compiling cleanly with clang after
pull request 109.

There were two overloadings of `Post(const parser::DeclarationTypeSpec::Type &)`.
The one in DeclarationVisitor needed to call the one in DeclTypeSpecVisitor.
This was fixed by introducing a new function, SetDerivedDeclTypeSpec, to do
the equivalent thing.
