* tree-ssa-loop-im.c (UNANALYZABLE_MEM_ID): New define.
(MEM_ANALYZABLE): Adjust.
(record_mem_ref_loc): Move bitmap ops ...
(gather_mem_refs_stmt): ... here. Use the shared mem-ref for
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.
(ref_indep_loop_p): Assert we are not queried for the
unanalyzed mem.
