Introduce the beginning of a THIR unsafety checker This poses the foundations for the THIR unsafety checker, so that it can be implemented incrementally: - implements a rudimentary `Visitor` for the THIR (which will definitely need some tweaking in the future) - introduces a new `-Zthir-unsafeck` flag which tells the compiler to use THIR unsafeck instead of MIR unsafeck - implements detection of unsafe functions - adds revisions to the UI tests to test THIR unsafeck alongside MIR unsafeck This uses a very simple query design, where bodies are unsafety-checked on a body per body basis. This however has some big flaws: - the unsafety-checker builds the THIR itself, which means a lot of work is duplicated with MIR building constructing its own copy of the THIR - unsafety-checking closures is currently completely wrong: closures should take into account the "safety context" in which they are created, here we are considering that closures are always a safe context I had intended to fix these problems in follow-up PRs since they are always gated under the `-Zthir-unsafeck` flag (which is explicitely noted to be unsound). r? `@nikomatsakis` cc https://github.com/rust-lang/project-thir-unsafeck/issues/3 https://github.com/rust-lang/project-thir-unsafeck/issues/7 |
