[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:

This class helps in dealing with normal and subnormal numbers uniformly.
Moreover, since this class has been designed to handle all floating

a uniform manner.
The implementations of frexp and logb have been switched to use this new
class as it allows us to use just one implementation across all
different floating point formats.
