// The simplest one-parameter version of btrace automatically sets the
// timestamp with the system clock. The other versions can optionally set the
// timestamp manually, or pass additional data to be written to the log line.
//
// Example:
// Btrace("Start execution");
// ... code to benchmark ...
// Btrace("End execution");
//
// Use compute_benchmarks.py
// with the trace path "Start execution,End execution",
// to report the elapsed time between the two calls.
//
// Btrace will either output to standard atrace, or to a file if specified.
// The versions BtraceData also allow an int64_t to be included in the trace.
// Btrace without data payload.
