Pete Steinfeld 1746c8ed26 [flang] Fixed crash on forward referenced `len` parameter 
Summary:
Using a forward reference to define a `len` parameter causes a crash.
The underlying cause was that a previously declared type had an
erroneous expression for its `LEN` param value.  When this expression
was referenced to evaluate a subsequent expression, bad things happened.
I fixed this by putting in code to detect this case.
