"""
A simple bench runner which delegates to the ./dotest.py test driver to run the
benchmarks defined in the list named 'benches'.

You need to hand edit 'benches' to modify/change the command lines passed to the
test driver.

Use the following to get only the benchmark results in your terminal output:

    ./bench.py 2>&1 | grep -P '^lldb.*benchmark:'
