[PowerPC] vector shift word/double by element size - 1 use all ones (#139794)
Vector shift word or double requires a shift amount vector of 31 or 63
which is too big for splat immediate and requires a multi-instruction
sequence. However the PPC instructions only use 5 or 6 bits of the shift
amount vector elements so an all ones mask, which we can generate
efficiently, works.
