rs6000: Rework vsx_extract_<mode>
Extracting the left and right halfs of a vector are entirely different
operations. Things are simpler if they are separate define_insns, and
it is easy to get rid of the "wD" constraint use then.
This also give the variant that is a no-op copy its own alternative, of
length 0 (and this, cost 0, making it more likely RA will choose it.

* config/rs6000/vsx.md (vsx_extract_<mode>): Replace define_insn by a
define_expand. Split the contents to...
(*vsx_extract_<mode>_0): ... this. Rewrite.
(*vsx_extract_<mode>_1): ... and this. Rewrite.
