ager@chromium.org 70dcba4024 Exclude the bit-field bits from string hash codes. String hash codes
are always odd if the bit-field bits are included.

Modified a couple of debugger tests that relied on the ordering of
elements in descriptor arrays.  Descriptor arrays are sorted by
hash-code values, so the order changes if we change the hash code.
