PR60276 fix for single-lane SLP
When enabling single-lane SLP and not splitting groups the fix for
PR60276 is no longer effective since it for unknown reason exempted
pure SLP. The following removes this exemption, making
gcc.dg/vect/pr60276.c PASS even with --param vect-single-lane-slp=1
PR tree-optimization/60276
* tree-vect-stmts.cc (vectorizable_load): Do not exempt
pure_slp grouped loads from the STMT_VINFO_MIN_NEG_DIST
restriction.
