Syncing against despite it only being a couple of days ago to make the migration from git-subtree to josh-sync easier.

atomic volatile: add intrinsics

Extend the atomic load/store intrinsics to also support volatile atomic load/store.
Tracking issue: rust-lang#158947.
Library APIs that use these intrinsics will be added inn a future PR.

The GCC and cranelift implementations ignore the volatile flag, not sure how that should be implemented for them.
