27062 already, reset in_changed_variables flag for it and propagate
27063 cur_loc_changed over to the new variable. On empty var
27064 always set cur_loc_changed. Set in_changed_variables on whatever
27065 var is added to changed_variables.
27066 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
27067 Use shared_var_p. When removing loc that is equal to cur_loc,
27068 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
27069 end, don't set it to something else, just call variable_was_changed.
27070 (delete_slot_part): Use shared_var_p. When cur_loc equals to
27071 loc being removed, clear cur_loc and set cur_loc_changed.
27072 Set cur_loc_changed if all locations have been removed.

27074 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

27078 cur_loc_changed of variables which had to change cur_loc and

27080 had to change cur_loc.

27089 first loc_chain location if NULL before. Always use just
27090 cur_loc instead of first loc_chain location. When cur_loc_changed
27091 is false, when not --enable-checking=rtl just don't emit any note.
27092 When rtl checking, compute the note and assert it is the same
27093 as previous note. Clear cur_loc_changed and in_changed_variables
