To accomplish this, we alter the checks in
rustc::middle::stability
touse the
StabilityLevel
defined insyntax::attr
(which includes theversion in which the feature was stabilized) rather than the local
StabilityLevel
in the same module, and make thedeclared_stable_lang_features
field ofsyntax::feature_gate::Features
hold a Vec of feature-name, spantuples (in analogy to the
declared_lib_features
field) rather thanjust spans.
Fixes #33394.
