2a43e78c17 [flang] Improvements to name resolution in data statements 
Handle variables in data statements differently from implied dos:
If a variable is first mentioned in a data statement, it is implicitly
declared in the current scope (and subsequent type declarations only
confirm the type).
In the implied do case, the only variables that can be implicitly
declared are the iteration variables. They must be created in the new
ImpliedDos scope. There must be one such scope for each data-stmt-object
because the variable name can be reused.

Resolve references to named constants, e.g. in complex-literal-constant
and data-stmt-value. This requires changing the handling of
named-constant-def as that is a definition, not a reference.

da46e49a01 [flang] Resolve namelist group and object names 
Namelist groups are represents by symbols with `NamelistDetails`.
Those contain a list of symbols representing the objects in the group.
References to namelist groups in io-control-spec are resolved.

In `.mod` files, namelist groups are written out at the end of the
module specification section. This is so that the declarations of the
objects in the namelist group appear before they are referenced.

42d7ac3e36 [flang] Fix link error from last integration 
We need to be able to analyze the `Variable` in a `Selector` and an
expression. That worked in a previous iteration of `expression.h` by
analyzing each variant of `Variable`.

This fix adds an explicit public function to analyze a Variable and
return a `MaybeExpr`.
