Some of the existing utils in utils/UnitTest/Test.h have been moved to
this new library.

Summary:
This patch adds a benchmarking infrastructure for llvm-libc memory functions.
In a nutshell, the code can benchmark small and large buffers for the memcpy, memset and memcmp functions.
It also produces graphs of size vs latency by running targets of the form `render-libc-{memcpy|memset|memcmp}-benchmark-{small|big}`.
The configurations are provided as JSON files and the benchmark also produces a JSON file.
This file is then parsed and rendered as a PNG file via the `render.py` script (make sure to run `pip3 install matplotlib scipy numpy`).
The script can take several JSON files as input and will superimpose the curves if they are from the same host.
TODO:
- The code benchmarks whatever is available on the host but should be configured to benchmark the -to be added- llvm-libc memory functions.
- Add a README file with instructions and rationale.
- Produce scores to track the performance of the functions over time to allow for regression detection.

Header files included wrongly using <...> are now included using the
internal path names as the new unittest framework allows us to do so.
