Found that now too.  Anyway, I believe (if there is no performance issue) I can
just tweak rs6000_expand_vector_extract this way, and the stve*x patterns would
need to be fixed anyway, though, because it hardly can have the extra argument,
it couldn't be VEC_SELECT, but I guess a scalar store with =Z or some similar
constraint that forces reg or reg+reg, with source being jus tthe unspec
UNSPEC_STVE with the vector as argument thereof.
