This stabilizes a subset of the `-Clinker-features` components on x64 linux: the lld opt-out. The opt-in is not stabilized, as interactions with other stable flags require more internal work, but are not needed for stabilizing using rust-lld by default. Similarly, since we only switch to rust-lld on x64 linux, the opt-out is only stabilized there. Other targets still require `-Zunstable-options` to use it.
