rollup merge of rust-lang#19653: frewsxcv/rm-reexports

Brief note: This does *not* affect anything in the prelude

Part of rust-lang#19253

All this does is remove the reexporting of Result and Option from their
respective modules. More core reexports might be removed, but these ones
are the safest to remove since these enums (and their variants) are included in
the prelude.

Depends on rust-lang#19407 which is merged, but might need a new snapshot
