* tree-ssa-loop-im.c (UNANALYZABLE_MEM_ID): New define.
(MEM_ANALYZABLE): Adjust.

unanalyzable refs, do not record locations for it.
(analyze_memory_references): Allocate ref zero as shared
unanalyzable ref.
(refs_independent_p): Do not test for unanalyzed mems here.
(ref_indep_loop_p_1): Special-case disambiguation against
the unanalyzed ref.
