Review feedback: add unstable marker to Placer API and put in bound that now works.

fix doc-tests by opting into `placement_in_syntax` feature where necessary.

fix pretty printing tests by opting into the features that the expanded code needs.

Update suggestion from parenthesized-box-expr-message to reflect new output spacing.

review feedback: Use checked-arith instead of saturated-arith for `push_unsafe!` and `pop_unsafe!`.

review feedback: common-subexpression-elim across functions in pushpop_safe impl.

update compile-fail/pushpop-unsafe-rejects.rs to reflect switch from saturated to checked arith.
