35414 (variable_canonicalize): Remove.
35415 (shared_var_p): New inline function.
35416 (unshare_variable): Maintain cur_loc_changed and

35418 replace it there with new_var. Just copy cur_loc instead of
35419 resetting it to something else.

35439 already, reset in_changed_variables flag for it and propagate
35440 cur_loc_changed over to the new variable. On empty var
35441 always set cur_loc_changed. Set in_changed_variables on whatever
35442 var is added to changed_variables.
35443 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
35444 Use shared_var_p. When removing loc that is equal to cur_loc,
35445 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
35446 end, don't set it to something else, just call variable_was_changed.
35447 (delete_slot_part): Use shared_var_p. When cur_loc equals to

35451 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
35452 allocated. Always create SUBREGs if simplify_subreg failed.
35453 Prefer to use cur_loc, when that fails and still in

35455 cur_loc_changed of variables which had to change cur_loc and
35456 compute elcd->cur_loc_changed if any of the subexpressions used
35457 had to change cur_loc.
35458 (vt_expand_loc): Adjust to pass arguments in

35463 that weren't used for any other decl in current

35465 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
35466 first loc_chain location if NULL before. Always use just
35467 cur_loc instead of first loc_chain location. When cur_loc_changed
35468 is false, when not --enable-checking=rtl just don't emit any note.
35469 When rtl checking, compute the note and assert it is the same
35470 as previous note. Clear cur_loc_changed and in_changed_variables
35471 at the end before removing from changed_variables.
35472 (check_changed_vars_3): New function.
