re PR tree-optimization/30562 (remove unused variable is removing a referenced variable (in STORED_SYMS or LOADED_SYMS))
PR 30562
* tree-flow.h (struct var_ann_d): Remove field 'is_used'.
Update all users.
* tree-ssa-alias.c (compute_is_aliased): Remove. Update all
users.
(init_alias_info):
* tree-ssa-live.c (remove_unused_locals): Do not remove
TREE_ADDRESSABLE variables.
* tree-ssa-structalias.c (compute_points_to_sets): Tidy.
* tree-ssa-operands.c (add_virtual_operand): Remove argument
FOR_CLOBBER. Update all users.
If VAR has an associated alias set, add a virtual operand for
it if no alias is found to conflict with the memory reference.
