// rdar://77217762 – The increment_profiler_counter in $foo gets optimized out by
// LLVM function optimization, but make sure we still emit the name data which
// is required by the coverage record.
// Make sure both the legacy and new pass manager work.
// We need to disable SIL optimizations to ensure LLVM optimizes out the
// profiler increment.
