1599d09041 [flang] Update the grammar with team-value 
Everywhere we had `team-variable` except for the FORM TEAM statement is
now `team-value`, according to the N2162 draft standard. The grammar
and parse tree are updated to reflect that.

The addition of the production for `team-value` caused productions
R1177-R1181 to have their numbers increased by one.

b60fd092f5 [flang] Simplify CommonStmt in parse tree 
The grammar requires parsing the first common block in a common stmt
differently from the others: the '//' is optional for the blank common.

But once it's parsed, it is easier to work with if each is represented
as a `parser::CommonStmt::Block`. This is achieved by using the same
constructor for `CommonStmt` but then including the first block in
the list of blocks.

daa0b054ba [flang] Change formatting of common::visitors{} 
Including a comma after the last lambda in a `common::visitors{}` list
causes clang-format to do a better job of formatting them.

Add that recommendation to C++style.md, insert the missing commas,

03435d981d [flang] Use fundamental types in overloadings of Unparse. 
Different systems map std::size_t, string::size_type, etc. to different
fundamental types. To ensure they are all covered, make the overloadings
of Unparse for integer types use only fundamental types.

This fixes compilations problems on Darwin and *BSD systems.

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.
