Optimize `incompatible_msrv` lint
This limits repeated lookups in pre-checks (to determine if a MSRV should be checked), especially when those require locking up an interner: - The `core` crate is looked up once when creating the lint, instead of comparing the crate name with `sym::core` at every check. - `span.ctxt().outer_expn_data()` is lookup up only once.
