The [THIR] is a shallow wrapper around [HIR], with datatypes that mirror the [HIR] datatypes.
For example, instead of `-x` being a `thir::ExprKind::Neg(thir::Expr)`
(a deep copy), it is a `thir::ExprKind::Neg(hir::Expr)` (a shallow copy).
This shallowness enables the [THIR] to represent all datatypes that [HIR] has, but
without having to create an in-memory copy of the entire [HIR].
