re PR tree-optimization/45633 (internal compiler error: verify_stmts failed)
PR tree-optimization/45633
* tree-cfg.c (verify_gimple_assign_binary): Allow
MINUS_EXPR with lhs and rhs1 pointer vector and
rhs2 sizetype vector.
* expr.c (expand_expr_real_2) <case PLUS_EXPR>: For pointer
or vector pointer use TER to optimize pointer subtraction.
* gcc.dg/vect/pr45633.c: New test.
