The benchmark results in several example files have been updated. This
commit reflects slight variations in performance measurements for
various test cases, including closure scope, data structures,
destructuring, higher-order functions, macros, and tuple operations.
This commit updates the benchmark timings and repeat counts for various
example files. The `tester.rs` script has been modified to:
- Correctly parse and use the `Benchmark-Repeat` directive.
- Implement an adaptive sampling mechanism for more accurate median
calculation, especially for long-running benchmarks.
- Improve the logic for updating and inserting benchmark and repeat
lines in example files.
- Handle potential compilation and runtime errors during benchmark
execution.
