* tree-ssa.c (maybe_optimize_var): New function split out from ...
(execute_update_addresses_taken): ... here.
(non_rewritable_mem_ref_base): Likewise.
(execute_update_addresses_taken): Do not iterate over all referenced
vars but just all local decls and parms.
Properly check call and asm arguments and rewrite call arguments.
* gcc.dg/pr44971.c: New testcase.
* gcc.c-torture/compile/pr44988.c: Likewise.
