PR target/79799
* config/rs6000/rs6000.c (rs6000_expand_vector_init): Add support
for doing vector set of SFmode on ISA 3.0.
* config/rs6000/vsx.md (vsx_set_v4sf_p9): Likewise.
(vsx_set_v4sf_p9_zero): Special case setting 0.0f to a V4SF
element.
(vsx_insert_extract_v4sf_p9): Add an optimization for inserting a
SFmode value into a V4SF variable that was extracted from another
V4SF variable without converting the element to double precision
and back to single precision vector format.
(vsx_insert_extract_v4sf_p9_2): Likewise.
