32937 (unshare_variable): Maintain cur_loc_changed and

32939 replace it there with new_var. Just copy cur_loc instead of

32960 already, reset in_changed_variables flag for it and propagate
32961 cur_loc_changed over to the new variable. On empty var
32962 always set cur_loc_changed. Set in_changed_variables on whatever
32963 var is added to changed_variables.
32964 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32965 Use shared_var_p. When removing loc that is equal to cur_loc,
32966 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32967 end, don't set it to something else, just call variable_was_changed.
32968 (delete_slot_part): Use shared_var_p. When cur_loc equals to

32972 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
32973 allocated. Always create SUBREGs if simplify_subreg failed.
32974 Prefer to use cur_loc, when that fails and still in

32976 cur_loc_changed of variables which had to change cur_loc and
32977 compute elcd->cur_loc_changed if any of the subexpressions used
32978 had to change cur_loc.
32979 (vt_expand_loc): Adjust to pass arguments in

32984 that weren't used for any other decl in current

32986 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
32987 first loc_chain location if NULL before. Always use just
32988 cur_loc instead of first loc_chain location. When cur_loc_changed
32989 is false, when not --enable-checking=rtl just don't emit any note.
32990 When rtl checking, compute the note and assert it is the same
32991 as previous note. Clear cur_loc_changed and in_changed_variables
32992 at the end before removing from changed_variables.
32993 (check_changed_vars_3): New function.
