Extended Description

The attached crashes sac2c while inserting symbolic array attributes.
The direct problem is that the SAA code presumes that the
returnexprs code always has a funcond as its SSAASSIGN node.
However, CF has removed the funcond (due to an always-true or 
always-false predicate, and replaced it with an N_num.
Presumably, either CF has to be more conservative about chucking
code away, or the SAA stuff has to be more intelligent about
what it expects to see when it is generating code to
ship non-formal results to the calling function.
