(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
generate temporaries for loop bounds that might contain function calls

were several instances of the same code in different locations in the
compiler; this checkin completes the replacement of all of these
instances with calls to a common subprogram.

corresponding objects exported by a-exexpr, instead of hardcoded dummy
