coverage: Store the number of counters/expressions in function coverage info
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.
