Empty hash table fix in .debug_names reader
The handling of an empty hash table in the .debug_names reader is
slightly wrong.
Currently the code assumes there is always an array of hashes.
However, section 6.1.1.4.5 Hash Lookup Table says:
The optional hash lookup table immediately follows the list of
type signatures.
and then:
The hash lookup table is actually two separate arrays: an array of
buckets, followed immediately by an array of hashes.
My reading of this is that the hash table as a whole is optional, and
so the hashes will not exist in this case. (This also makes sense
because the hashes are not useful without the buckets anyway.)
