…const_check function
This test demonstrates the existing crash, and will be migrated to a successful coverage test in a subsequent commit. Co-Authored-By: Rachel Barker <rachel.barker@ferrous-systems.com>
Compile-time-only functions don't generate code, so instrumenting them for coverage is useless. This also avoids an ICE when trying to get the function's symbol name for an unused-function record, which can occur when instrumenting `core`.

…tatic-bound, r=jackh726 avoid spurious lifetime diagnostic in async generic case Fixes rust-lang#115376. Issue rust-lang#115376 reports duplicate lifetime diagnostics for a small async generic example where rustc already emits the real `T: 'static` error. Additionally, it emits diagnostics requiring the same generic type to outlive a shorter anonymous lifetime My PR keeps the real static-bound diagnostic and filters same-span weaker type-test diagnostics for the same generic when the failed `G: 'static` bound already covers them. New regression test verifies that the async example emits only the real E0310 diagnostic. One existing borrowck test was updated for the same diagnostic cleanup
…, r=oli-obk Reflection refactor ptrs Tracking issue rust-lang#146922 Part of the [Refactoring to many methods](https://rust-lang.zulipchat.com/#narrow/channel/572285-goals.2Freflection/topic/Refactoring.20to.20many.20methods/with/592226560) reflection subgoal. See that for the full context. In short for various reasons we are moving from an enum `TypeKind` where the variants hold the types information to one that just tells you the type kind. Separate methods on `TypeId` provide a way to get to the data that used to be in the variant. Since function pointers have a lot of fields it felt better to keep the `FnPtr` struct we have now then add an intrinsic for each field. r? @oli-obk
Make comptime functions ineligible for coverage - rust-lang#159777 - rust-lang#161808 --- As reported in rust-lang#161808, the assertion in rust-lang#159777 causes the compiler to ICE when it tries to generate an unused-function record for comptime functions, because comptime functions aren't allowed to have a symbol name. This can occur when trying to instrument `core`, for example. Compile-time-only functions don't generate code, so instrumenting them for coverage is useless anyway. This PR therefore makes them ineligible for coverage, which avoids the problem.
… r=oli-obk add test ensuring we refuse to const-eval the body of a rustc_do_not_const_check function IMO this is crucial, to ensure that we cannot break users by changing the body of such a function to something no-longer-const-compatible. r? @oli-obk
