PR tree-optimization/52445
* tree-ssa-phiopt.c (struct name_to_bb): Remove ssa_name field,
add ssa_name_ver, offset and size fields and change store field
to bool.
(name_to_bb_hash, name_to_bb_eq): Adjust for the above changes.
(add_or_mark_expr): Likewise. Only consider previous stores
with the same size and offset.
(nt_init_block): Only look at gimple_assign_single_p stmts,
doesn't look at rhs2.
* gcc.dg/pr52445.c: New test.
