Improved robustness of test_hash_value("hello").
The optimizer threw away the string "hello" from a() before starting on b(),
there was thus a risk that the string "hello" in b() would be allocated
somewhere else and get a different hash value. This seems to have happened
more frequently on 64-bit pikes than on 32-bit pikes, but the potential for
the problem was there on both.
