IIRC, the idea was that if memset_explicit() is recognized by compilers
then they can make better decision. E.g if the data is held in a
register without any further copy in memory, then compiler can just
clear the register instead of spilling it onto the stack and calling
memset_explicit() on it.
But that's not really relevant for libcs trying to add support for it.
Both of them can co-exist.
