Move memory zeroing to a compiled function in a new source file. Cast
the pointer to volatile before writing to it. At least for various
versions of GCC, Clang, and ICC on x86-64, this does cause the
compiler to emit a simple byte-at-a-time loop, and at least in non-LTO
builds the compiler won't optimize the call away. For dealing with
LTO, probably would have to do some kind of complicated side-effect.
