Generating the coverage map @tmandry @wesleywiser rustc now generates the coverage map and can support (limited) coverage report generation, at the function level. Example commands to generate a coverage report: ```shell $ BUILD=$HOME/rust/build/x86_64-unknown-linux-gnu $ $BUILD/stage1/bin/rustc -Zinstrument-coverage \ $HOME/rust/src/test/run-make-fulldeps/instrument-coverage/main.rs $ LLVM_PROFILE_FILE="main.profraw" ./main called $ $BUILD/llvm/bin/llvm-profdata merge -sparse main.profraw -o main.profdata $ $BUILD/llvm/bin/llvm-cov show --instr-profile=main.profdata main ```  r? @wesleywiser Rust compiler MCP rust-lang/compiler-team#278 Relevant issue: #34701 - Implement support for LLVMs code coverage instrumentation
