  // During parsing, all constant expressions are folded to constant union nodes. The expressions that
  // have been folded may have had precision qualifiers, which should affect the precision of the
  // consuming operation. If the folded constant union nodes are written to output as such they won't
  // have any precision qualifiers, and their effect on the precision of the consuming operation is
  // lost.
  //
  // RecordConstantPrecision is an AST traverser that inspects the precision qualifiers of constants
  // and hoists the constants outside the containing expression as precision qualified named variables
  // in case that is required for correct precision propagation.
