The function listings in api.td are removed. The same lists are now deduced using the information
in entrypoints.txt.

This class is currently used by two tools: HdrGen and PrototypeTestGen.
We will be adding more tools based on this class so it is convenient to
keep it in a util library of its own.
Summary:
This patch aims to add integration tests to check the following:
1) Header files are generated as expected.
2) Libc functions have the correct public name.
3) Libc functions have the correct return type and parameter types.
4) Symbols are exposed in the public lib.a files.

Summary:
Made all header files consistent based of this documentation: https://llvm.org/docs/CodingStandards.html#file-headers.
And did the same for all source files top of file comments.

A target to generate the std C threads.h file has been added. This
utilizes the new feature added in this change.

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.
