27073 (unshare_variable): Maintain cur_loc_changed and

27075 replace it there with new_var. Just copy cur_loc instead of

27096 already, reset in_changed_variables flag for it and propagate
27097 cur_loc_changed over to the new variable. On empty var
27098 always set cur_loc_changed. Set in_changed_variables on whatever
27099 var is added to changed_variables.
27100 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
27101 Use shared_var_p. When removing loc that is equal to cur_loc,
27102 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
27103 end, don't set it to something else, just call variable_was_changed.
27104 (delete_slot_part): Use shared_var_p. When cur_loc equals to

27108 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
27109 allocated. Always create SUBREGs if simplify_subreg failed.
27110 Prefer to use cur_loc, when that fails and still in

27112 cur_loc_changed of variables which had to change cur_loc and
27113 compute elcd->cur_loc_changed if any of the subexpressions used
27114 had to change cur_loc.
27115 (vt_expand_loc): Adjust to pass arguments in

27120 that weren't used for any other decl in current

27122 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
27123 first loc_chain location if NULL before. Always use just
27124 cur_loc instead of first loc_chain location. When cur_loc_changed
27125 is false, when not --enable-checking=rtl just don't emit any note.
27126 When rtl checking, compute the note and assert it is the same
27127 as previous note. Clear cur_loc_changed and in_changed_variables
27128 at the end before removing from changed_variables.
