c++: broken direct-init with trailing array member [PR114439]

can_init_array_with_p is wrongly saying that the init for 's' here:

  struct S {
    int *list = arr;
    int arr[];
  };

  struct A {
    A() {}
    S s[2]{};
  };

is invalid.  But as process_init_constructor_array says, for "non-constant
initialization of trailing elements with no explicit initializers" we use
a VEC_INIT_EXPR wrapped in a TARGET_EXPR, built in process_init_constructor.

Unfortunately we didn't have a test for this scenario so I didn't
realize can_init_array_with_p must handle it.

	PR c++/114439

gcc/cp/ChangeLog:

	* init.cc (can_init_array_with_p): Return true for a VEC_INIT_EXPR
	wrapped in a TARGET_EXPR.

gcc/testsuite/ChangeLog:

	* g++.dg/init/array65.C: New test.
