cleanup: Change LEN_MASK into MASK_LEN

Hi.

Since start from LEN_MASK_GATHER_LOAD/LEN_MASK_SCATTER_STORE, COND_LEN_* patterns,
the order of len and mask is {mask,len,bias}.

The reason we make "mask" argument comes before "len" is because we want to keep
the "mask" location same as mask_* or cond_* patterns to make use of current codes flow
of mask_* and cond_*. Otherwise, we will need to change codes much more and make codes
hard to maintain.

Now, we already have COND_LEN_*, it's naturally that we should rename "LEN_MASK" into "MASK_LEN"
to keep name scheme consistent.

This patch only changes the name "LEN_MASK" into "MASK_LEN".
No codes functionality change.
