tokhash: Speed up the rejection of unhashed values
...
Speed up the rejection of unhashed values (typically identifiers) by
filling unused hash slots with a large value (but not so large that
it is likely to overflow.) This means those values will be rejected
already by the range check, not needing strcmp().

tokhash.pl: "ix" should have the same width as the "hash" arrays
...
For correctness in case of a very "linear" graph, "ix" needs to have
the same width as the "hash" arrays.

phash.ph: use a bipartite graph to reduce the storage requirements
...
Since we fold the f- and g-functions together, if we guarantee that g is
bipartite, we can make g twice the size of f without cost. This greatly
improves the odds of generating a smaller hash.

Suppress IP-relative only for fs: and gs: overrides

AMD has (undocumented) segment limits even in 64-bit mode, so people

IP-relative still applies.
