473658dd86 [flang] Fix test_folding.sh to work on MacOS 
There were a couple of small incompatibilities:
- There is no `ldd` on MacOS; instead use `otools -L`.
  This has not been tested when libpgmath is linked in to f18.
- `wc` outputs spaces where on Linux it outputs tabs; change how
  the number of lines is extracted to work on both.

Also, fix a bug: change `passed_warnings` to `$passed_warnings`.

f62528535e [flang] Folding improvments: 
- 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.

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.
