This aligns with common code which already uses this flag. We have
to add another local prototype to fix the failure, and add another
local decl for the SIM_DESC type. Unwinding these will require a
lot more work & conversions in the process, so going with the decl
for now unblocks the warning unification.
The sim keeps track of which allocations are zero-ed internally (via
zalloc) and then calls a helper "zfree" function rather than "free".
But this "zfree" function simply calls "free" itself. Since I can
see no point in this and it is simply useless overhead, punt it.
The only real change is in hw-alloc.c where we remove the zalloc_p
tracking, and sim-utils.c where zfree is delete. The rest of the
changes are a simple `sed` from "zfree" to "free".
