3845 var is added to changed_variables.
3846 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
3847 Use shared_var_p. When removing loc that is equal to cur_loc,

3858 cur_loc_changed of variables which had to change cur_loc and
3859 compute elcd->cur_loc_changed if any of the subexpressions used
3860 had to change cur_loc.

3869 first loc_chain location if NULL before. Always use just
3870 cur_loc instead of first loc_chain location. When cur_loc_changed
3871 is false, when not --enable-checking=rtl just don't emit any note.
3872 When rtl checking, compute the note and assert it is the same
3873 as previous note. Clear cur_loc_changed and in_changed_variables
3874 at the end before removing from changed_variables.
3875 (check_changed_vars_3): New function.
