further optimize non-store-motion LIM

This removes useless work from LIM when store-motion is disabled.

2020-11-16   Richard Biener  <rguenther@suse.de>

* tree-ssa-loop-im.c (analyze_memory_references): Add
store_motion parameter and elide unnecessary work.
(tree_ssa_lim_initialize): Likewise.
(loop_invariant_motion_in_fun): Pass down store_motion.
