It is only ever called with a newly allocated slice.
This clearing code dates back to the C version of the compiler,
in which the function started like this:
static void
gengcmask(Type *t, uint8 gcmask[16])
{
...
memset(gcmask, 0, 16);
if(!haspointers(t))
return;
That memset was required for C, but not for Go.
