  [flang] Better error handling for PDT constant expression (#130637)

We currently don't consider an integer division to be a constant
expression unless its divisor is known and nonzero. This produces a
weird result in the linked test; do better.

Fixes https://github.com/llvm/llvm-project/issues/130534.
