Fix a few issues found when trying to build the benchmark:
Errors
1. Unable to find include "src/__support/macros/config.h" in
LibcMemoryBenchmarkMain.cpp
Warnings
2. Unused variable warning `Index` in MemorySizeDistributions.cpp
3. Fix deprecation warning for const-ref version of `DoNotOptimize`.
warning: 'DoNotOptimize<void *>' is deprecated: The const-ref version of
this method can permit undesired compiler optimizations in benchmarks

As specified in the docs,
1) raw_string_ostream is always unbuffered and
2) the underlying buffer may be used directly
( 65b13610a5226b84889b923bae884ba395ad084d for further reference )
Avoid unneeded calls to raw_string_ostream::str(), to avoid excess indirection.

This also allows to run the distribution benchmarks in other frameworks
like the Google Benchmark facility.

All distributions (expect D) have been updated using 7 days worth of data.
Distributions are smoother.
This patch also moves data from header file to individual csv file. It
helps the editor and allows easier export/plotting of the data.

The benchmarking infrastructure can now run in two modes:
- Sweep Mode: which generates a ramp of size values (same as before),
- Distribution Mode: allows the user to select a distribution for the size paramater that is representative from production.
The analysis tool has also been updated to handle both modes.

This patch adds memory function size distributions sampled from different applications running in production.
This will be used to benchmark and compare memory functions implementations.
