Coverage codegen can now allocate arrays based on the number of counters/expressions originally used by the instrumentor. The existing query that inspects coverage statements is still used for determining the number of counters passed to `llvm.instrprof.increment`. If some high-numbered counters were removed by MIR optimizations, the instrumented binary can potentially use less memory and disk space at runtime. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
