rs6000: lxsdux / stxsdux do not exist
Our md files refer to {l,st}xsd%U<n>x, but no {l,st}xsdux insns exist.
This patch removes the update forms. All these use constraint "Z"
which does not allow update form, so there is no practical difference.
* config/rs6000/rs6000.md (*mov<mode>_hardfloat32): Remove %U from the
lxsdx and stxsdx alternatives.
(*mov<mode>_hardfloat64): Ditto.
* config/rs6000/vsx.md (*vsx_extract_<mode>_store): Ditto.
