Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on 64bit systems)
Rationale: only a minority of variants used almost half the size.
By keeping large members (especially in Option) behind a box
the memory cost is only payed when the large variants are needed.
This reduces the size Vec<Expr> needs to allocate.
