- Add location to non-fatal error message (context was not given
a location before folding in semantics).
- Avoid refolding expression from scratch several times (update GenericExprWrapper
after folding). So far, warning messages were generated twice per parametere init
expressions.

Use better names for template parameters of `LoopBounds`, and also
for the constructor arguments.
Use two overloadings of `loopBounds()` instead of `std::is_same_v<>`.

It is a common extension to allow DO loops with REAL variable and
bounds. The parse tree currently parses those with the variable
as `scalar-int-variable-name` and the bounds as `scalar-int-expr`.
That causes the INTEGER constraint to be enforced automatically.
Change the grammar and parse tree to treat them as `scalar-variable-name`
and `scalar-expr`. This allows the name and expression to be REAL,
but we will have to verify that they aren't any other type (in a future
change).
To accomplish this, add a template parameter to `LoopBounds` for the type
of the variable name (always `Scalar<Name>` or `Scalar<Integer<Name>>`).
We sometimes need names for the instantiations of `LoopBounds` so add
type aliases like `LoopControl::Bounds` for each one.

Change the order in which names are resolved. Before resolving names
in the execution part of a subprogram we need to know the interface
of contained subprograms. This is because the type of some construct
entities can depend on the return type of contained functions, e.g.
```
associate(x => f())
end associate
contains
function f()...
```
To do this, we now build a tree rooted at each program unit with
child nodes corresponding to subprograms contained in the parent.
This provides flexibility in choosing an order to resolve names.
The current implementation processes all specification parts before
any execution parts. This ensures contained subprogram interfaces
are know before analyzing constructs like ASSOCIATE.
Resolving a specification part involves first adding
`SubprogramNameDetails` symbols for each contained subprogram, then
processing the statement that introduces the program unit (`ModuleStmt`,
`SubroutineStmt`, etc.), then visiting all of the statements in the
specification part.
If it proves necessary, we can add a phase to do implicit declarations
in the execution part before processing the specification part of
contained subprograms.

Previously we maintained a stack of ImplicitRules in parallel with
the Scope stack. Change to maintaining a mapping from Scope to
ImplicitRules.
This makes things simpler in some cases: Block scopes don't have their
own implicit rules. And submodule scopes aren't just pushed and popped.
This will also help with future changes to the order in which scopes
are processed.
