// 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.
