testsuite/97494 - adjust gcc.dg/vect/slp-11b.c
Support for loop SLP splitting exposed that slp-11b.c has
folding that breaks SLP discovery which isn't what was intended
when the testcase was written. The following makes it SLP-able
and "only" run into the issue that a load permutation is required.
And tries to adjust the target selectors accordingly.
