Fix logic bug in Cilk Plus array expansion
gcc/cp/ChangeLog:
* cp-array-notation.c (cp_expand_cond_array_notations): Return
error_mark_node only if find_rank failed, not if it was
successful.
gcc/testsuite/ChangeLog:
* c-c++-common/cilk-plus/AN/an-if.c: Check that the original
dump does not contain an error_mark_node.
* c-c++-common/cilk-plus/CK/pr60469.c: Likewise.
* c-c++-common/cilk-plus/AN/fn_ptr-2.c: New xfail'd test.
