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
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.

Summary:
To get the target order correct, the benchmarks directory has been moved
one level higher. Previously, it was living in the utils directory. The
utils directory is a collection of utils which are to be used by the
tests and implementations. However, benchmarks *use* the
implementations. So, moving it out of utils helps us setup proper
target level dependencies.
