rollup merge of #23863: pnkfelix/arith-oflo-const-eval
const_eval : add overflow-checking for {`+`, `-`, `*`, `/`, `<<`, `>>`}.

One tricky detail here: There is some duplication of labor between `rustc::middle::const_eval` and `rustc_trans::trans::consts`. It might be good to explore ways to try to factor out the common structure to the two passes (by abstracting over the particular value-representation used in the compile-time interpreter).
