[PATCH] D48879: [XRay][test-suite] Benchmarks for profiling mode implementation

I patched it in (on the 7.0 branch because that's what I have handy) but it crashes:

If I run it directly:

  $ /work/llvm-release-test/branches_release_70/test-suite-build/MicroBenchmarks/XRay/ProfilingMode/profiling-bench --benchmark_format=csv > /work/llvm-release-test/branches_release_70/test-suite-build/MicroBenchmarks/XRay/ProfilingMode/Output/profiling-bench.test.bench.csv

it runs fine.

I'm guessing lit does something to the environment that makes the test fail.
