Move OS::MemCopy and OS::MemMove out of platform to utils · a5a21a0d

jochen@chromium.org authored May 26, 2014

Since both are jitted on some platforms and depend on codegen, they
don't belong to the platform abstraction. At the same time, I can't put
them to codegen.h, as this would introduce cyclic dependencies.
