We only need to take action when the next block cannot be added to the current chain, but the logic is much simpler if we express it in terms of when the block _can_ be added.
The channel's `Block::new` was causing a stack overflow because it held 32 item slots, instantiated on the stack before moving to `Box::new`. The 32x multiplier made modestly-large item sizes untenable. That block is now initialized directly on the heap. Fixes rust-lang#102246

coverage: Simplify parts of coverage graph creation This is a combination of three semi-related simplifications to how coverage graphs are created, grouped into one PR to avoid conflicts. There are no observable changes to the output of any of the coverage tests.
…ouxu coverage: Extract safe FFI wrapper functions to `llvm_cov` This PR takes all of the inline `unsafe` calls in coverage codegen, and all the safe wrapper functions in `coverageinfo/mod.rs`, and moves them to a new `llvm_cov` submodule that is dedicated to safe FFI wrapper functions. This reduces the mixing of abstraction levels in the rest of coverage codegen. As a follow-up, this PR also tidies up the names and signatures of several of the coverage FFI functions.
Simplify FFI calls for `-Ztime-llvm-passes` and `-Zprint-codegen-stats` The existing code for these unstable LLVM-infodump flags was jumping through hoops to pass an allocated C string across the FFI boundary, when it's much simpler to just write to a `&RustString` instead.

The 32x multiplier made modestly-large item sizes untenable. That block is now initialized directly on the heap. Fixes rust-lang#102246 try-job: test-various
