…ult. The 'stable_features' lint helps people progress from unstable to stable Rust by telling them when they no longer need a `feature` attribute because upstream Rust has declared it stable. This compares to the existing 'unstable_features', which is used to implement feature staging, and triggers on *any* use of `#[feature]`.

This seems to give me errors like: IIRC all lints are set to Deny on stage2 builds. I think. |

@Manishearth huh, the unused features lint didn't change much here. maybe a problem in other rollup patches. i'll test this again locally. |

…notes_version_stabilized, r=brson stable features lint warning mentions version stabilized To accomplish this, we alter the checks in `rustc::middle::stability` to use the `StabilityLevel` defined in `syntax::attr` (which includes the version in which the feature was stabilized) rather than the local `StabilityLevel` in the same module, and make the `declared_stable_lang_features` field of `syntax::feature_gate::Features` hold a Vec of feature-name, span tuples (in analogy to the `declared_lib_features` field) rather than just spans. Fixes rust-lang#33394.  r? @brson (tagging Brian because he [wrote](rust-lang#21958) the lint)
