Implement flow analysis for dispatch sharing, and use it in the Silver compiler #837

Closed krame505 closed 3 months ago

krame505 commented 3 months ago

Fixes #812, fixes #810. Depends on #831.

Changes

This finishes support for dispatch sharing, and refactors the Silver compiler to use it.

Remove support for unique references and undecorates to. Uniqueness analysis is kept, but significantly condensed into a check for multiple non-mutually-exclusive sharing of the same tree.

Significant refactoring of the flow analysis, inherited completeness checking is now expressed as a rewriting process over a DecSiteTree decision tree. Introduced flow graphs for dispatch signatures. Updated and fix bugs with hidden transitive dependency checks.
