Tim Keith 351dc98948 [flang] Change parse tree to allow DO loop over REAL 
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.
