* tree-data-ref.h (DR_INNERMOST): New macro.
* tree-if-conv.c (innermost_loop_behavior_hash): New class for
hashing struct innermost_loop_behavior.
(ref_DR_map): Remove.
(innermost_DR_map): New map.
(baseref_DR_map): Revise comment.
(hash_memrefs_baserefs_and_store_DRs_read_written_info): Store DR
to innermost_DR_map accroding to its innermost loop behavior.
(ifcvt_memrefs_wont_trap): Get DR from innermost_DR_map according
to its innermost loop behavior.
(if_convertible_loop_p_1): Remove intialization for ref_DR_map.
Add initialization for innermost_DR_map. Record memory reference
in DR_BASE_ADDRESS if the reference is compound one or it doesn't
have innermost loop behavior.
(if_convertible_loop_p): Remove release for ref_DR_map. Release
innermost_DR_map.
