32930 (unshare_variable): Maintain cur_loc_changed and
32931 in_changed_variables fields. If var was in changed_variables,
32932 replace it there with new_var. Just copy cur_loc instead of
32933 resetting it to something else.

32943 (dataflow_set_preserve_mem_locs): Use shared_var_p. When

32953 already, reset in_changed_variables flag for it and propagate
32954 cur_loc_changed over to the new variable. On empty var
32955 always set cur_loc_changed. Set in_changed_variables on whatever
32956 var is added to changed_variables.
32957 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32958 Use shared_var_p. When removing loc that is equal to cur_loc,
32959 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32960 end, don't set it to something else, just call variable_was_changed.
32961 (delete_slot_part): Use shared_var_p. When cur_loc equals to
32962 loc being removed, clear cur_loc and set cur_loc_changed.

32965 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
32966 allocated. Always create SUBREGs if simplify_subreg failed.

32969 cur_loc_changed of variables which had to change cur_loc and
32970 compute elcd->cur_loc_changed if any of the subexpressions used
32971 had to change cur_loc.

32980 first loc_chain location if NULL before. Always use just
32981 cur_loc instead of first loc_chain location. When cur_loc_changed
32982 is false, when not --enable-checking=rtl just don't emit any note.
32983 When rtl checking, compute the note and assert it is the same
32984 as previous note. Clear cur_loc_changed and in_changed_variables
32985 at the end before removing from changed_variables.
