rs6000: Add len_load/len_store optab support

Define rs6000 specific len_load/len_store for the LEN_LOAD/LEN_STORE
internal function's expansion.  As the doc description of the
len_load/len_store optab shows, we should use V16QI to wrap those
available vector modes.

gcc/ChangeLog:

* config/rs6000/vsx.md (len_load_v16qi): New define_expand.
(len_store_v16qi): Likewise.
