[PATCH] test/rs6000: Add Power9 and up as vect_len target

Hi,

Power9 supports vector with length in bytes load/store, this patch
is to teach check_effective_target_vect_len_load_store to take it
and its laters as effective vector with length targets.

Also supplement the documents for has_arch_pwr*.

Bootstrapped/regtested on powerpc64le-linux-gnu P8.

Is it ok for trunk?

BR,
Kewen
