1044 and in_changed_variables and cur_loc_changed is false.

1058 already, reset in_changed_variables flag for it and propagate
1059 cur_loc_changed over to the new variable. On empty var
1060 always set cur_loc_changed. Set in_changed_variables on whatever
1061 var is added to changed_variables.
1062 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
1063 Use shared_var_p. When removing loc that is equal to cur_loc,
1064 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
1065 end, don't set it to something else, just call variable_was_changed.
1066 (delete_slot_part): Use shared_var_p. When cur_loc equals to

1074 cur_loc_changed of variables which had to change cur_loc and
1075 compute elcd->cur_loc_changed if any of the subexpressions used
1076 had to change cur_loc.

1084 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
1085 first loc_chain location if NULL before. Always use just
1086 cur_loc instead of first loc_chain location. When cur_loc_changed
1087 is false, when not --enable-checking=rtl just don't emit any note.
1088 When rtl checking, compute the note and assert it is the same
1089 as previous note. Clear cur_loc_changed and in_changed_variables
1090 at the end before removing from changed_variables.
1091 (check_changed_vars_3): New function.
