For memset, the size of used vector is decided by MIN(MOVE_MAX_PIECES,
STORE_MAX_PIECES).
Unless there's u-arch prefer big size vector for memcpy and small size
vector for memset, there's no need to have a separate option or tune
for it.
In general, x86 backend always prefer big size vector for memset due
to STLF issue.
