32925 already, reset in_changed_variables flag for it and propagate
32926 cur_loc_changed over to the new variable. On empty var
32927 always set cur_loc_changed. Set in_changed_variables on whatever
32928 var is added to changed_variables.
32929 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32930 Use shared_var_p. When removing loc that is equal to cur_loc,
32931 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32932 end, don't set it to something else, just call variable_was_changed.
32933 (delete_slot_part): Use shared_var_p. When cur_loc equals to
32934 loc being removed, clear cur_loc and set cur_loc_changed.
32935 Set cur_loc_changed if all locations have been removed.

32937 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

32941 cur_loc_changed of variables which had to change cur_loc and

32943 had to change cur_loc.

32952 first loc_chain location if NULL before. Always use just
32953 cur_loc instead of first loc_chain location. When cur_loc_changed
32954 is false, when not --enable-checking=rtl just don't emit any note.
32955 When rtl checking, compute the note and assert it is the same
32956 as previous note. Clear cur_loc_changed and in_changed_variables
32957 at the end before removing from changed_variables.
