re PR tree-optimization/79920 (Incorrect floating point results when compiling with -O3)

PR tree-optimization/79920
* tree-vect-slp.c (vect_create_mask_and_perm): Remove and inline
with ncopies == 1 to ...
(vect_transform_slp_perm_load): ... here. Properly compute
all element loads by iterating VF times over the group. Do
not handle ncopies (computed in a broken way) in
vect_create_mask_and_perm.
* gcc.dg/vect/pr79920.c: New testcase.
