(vsx_extract_v4sf): Delete alternative that hard coded element 0,
which never was matched due to the split occuring before register
allocation (and the code would not have worked on little endian
systems if it did match).  Allow extracts to go to the Altivec

vec_extracts when the element number is variable on 64-bit ISA
