sparc: Let memset return the address argument

[ Upstream commit 74cad25c076a2f5253312c2fe82d1a4daecc1323 ]

This makes memset follow the standard (instead of returning 0 on success). This
is needed when certain versions of gcc optimizes around memset calls and assume
that the address argument is preserved in %o0.
