13023 (shared_var_p): New inline function.
13024 (unshare_variable): Maintain cur_loc_changed and

13047 already, reset in_changed_variables flag for it and propagate
13048 cur_loc_changed over to the new variable. On empty var
13049 always set cur_loc_changed. Set in_changed_variables on whatever
13050 var is added to changed_variables.
13051 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
13052 Use shared_var_p. When removing loc that is equal to cur_loc,
13053 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
13054 end, don't set it to something else, just call variable_was_changed.
13055 (delete_slot_part): Use shared_var_p. When cur_loc equals to
13056 loc being removed, clear cur_loc and set cur_loc_changed.
13057 Set cur_loc_changed if all locations have been removed.
13058 (struct expand_loc_callback_data): New type.
13059 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
13060 allocated. Always create SUBREGs if simplify_subreg failed.
13061 Prefer to use cur_loc, when that fails and still in
13062 changed_variables (and seen first time) recompute it. Set
13063 cur_loc_changed of variables which had to change cur_loc and
13064 compute elcd->cur_loc_changed if any of the subexpressions used
13065 had to change cur_loc.
13066 (vt_expand_loc): Adjust to pass arguments in
13067 expand_loc_callback_data structure.
13068 (vt_expand_loc_dummy): New function.

13071 that weren't used for any other decl in current
13072 emit_notes_for_changes call call vt_expand_loc_dummy to update
13073 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
13074 first loc_chain location if NULL before. Always use just
13075 cur_loc instead of first loc_chain location. When cur_loc_changed
13076 is false, when not --enable-checking=rtl just don't emit any note.
13077 When rtl checking, compute the note and assert it is the same
13078 as previous note. Clear cur_loc_changed and in_changed_variables
13079 at the end before removing from changed_variables.
13080 (check_changed_vars_3): New function.
13081 (emit_notes_for_changes): Traverse changed_vars to call
