Auto merge of #32328 - jseyfried:coherence, r=nikomatsakis
resolve: Improve import failure detection and lay groundwork for RFC 1422 This PR improves import failure detection and lays some groundwork for RFC 1422. More specifically, it - Avoids recomputing the resolution of an import directive's module path. - Refactors code in `resolve_imports` that does not scale to the arbitrarily many levels of visibility that will be required by RFC 1422. - Replaces `ModuleS`'s fields `public_glob_count`, `private_glob_count`, and `resolved_globs` with a list of glob import directives `globs`. - Replaces `NameResolution`'s fields `pub_outstanding_references` and `outstanding_references` with a field `single_imports` of a newly defined type `SingleImports`. - Improves import failure detection by detecting cycles that include single imports (currently, only cycles of globs are detected). This fixes #32119. r? @nikomatsakis
