```
compiler-rt: optimize memcpy

The new memcpy function aims to be more generic than the previous
implementation which was adapted from an implementation optimized for
x86_64 avx2 machines. Even on x86_64 avx2 machines this implementation
should be generally be faster due to fewer branches in the small length
cases and generating less machine code.

Note that the new memcpy function no longer acts as a memmove.
