* tree-vect-slp.c (vect_get_and_check_slp_defs): For reduction
chains try harder with operand swapping and instead of
putting a shifted chain into the reduction operands put
a repetition of the final reduction op there as if we'd
reassociate the expression.
* gcc.dg/vect/slp-reduc-10a.c: New testcase.
* gcc.dg/vect/slp-reduc-10b.c: Likewise.
* gcc.dg/vect/slp-reduc-10c.c: Likewise.
* gcc.dg/vect/slp-reduc-10d.c: Likewise.
* gcc.dg/vect/slp-reduc-10e.c: Likewise.
