Guillaume Chatelet deae7e982a [libc] revamp memory function benchmark 
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.

Guillaume Chatelet c400e01c62 [libc][NFC] Add probability distributions for memory function sizes 
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.

Anthony Steinhauser ef36e8380a [libc] Using llvm_libc memcpy in mem* benchmarks. 
Currently the mem* benchmarks use memcpy from Glibc and memset from LLVM libc.
That's misleading and produces inconsistent results and behaviors.

This change makes Memcpy.cpp consistent with Memset.cpp:

Pavel Labath 9cb222e749 [cmake] Make gtest include directories a part of the library interface 
This applies the same fix that D84748 did for macro definitions.
Appropriate include path is now automatically set for all libraries
which link against gtest targets, which avoids the need to set
include_directories in various parts of the project.

Siva Chandra Reddy 438f7fc068 [libc][benchmarks] Link the memory benchmark exes to functions from LLVM libc. 
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.
