So I've opened rust-lang/stdarch#725 to set the edition of core::arch to 2018 unconditionally, and will hold all contributions to stdsimd until that PR and this PR are merged, because ensuring that the core::arch module remains compatible for both editions for all tier1 and tier2 targets is just too much of a pain.

(EDIT: I've just done a release of core_arch and std_detect so that if somebody hits any temporary issues they can use those from crates.io instead until this PR is merged).
