  Log Message:
  -----------
  [MLIR] Constant fold multiplies in deriveStaticUpperBound.

Summary:
This operation occurs during collapseParallelLoops, so we constant fold
them also to allow more situations of determining a loop invariant upper
bound when lowering to the GPU dialect from the Loop dialect.
