Add extra arguments and checks to the runtime support library so that
a call to the intrinsic functions MOD and MODULO with "denominator"
argument P of zero will cause a crash with a source location rather
than an uninformative floating-point error or integer division by
zero signal.

Additional work is required in lowering to (1) pass source file path and
source line number arguments and (2) actually call these runtime
library APIs instead of emitting inline code for MOD &/or MODULO.
