// FoldExpressions.cpp: Fold expressions. This may fold expressions so that the qualifier of the
// folded node differs from the qualifier of the original expression, so it needs to be done after
// parsing and validation of qualifiers is complete. Expressions that are folded:
//  1. Ternary ops with a constant condition.
//  2. Sequence aka comma ops where the left side has no side effects.
//  3. Any expressions containing any of the above.
