9b49e24e1f Feeble attempt at updating the documentation; remove Appendix B 
Feeble attempt to document 64-bit support.  Also, remove Appendix B since
we have been utterly useless at keeping it up to date, and it's redundant
with the processor manufacturer's documentation anyway.

b79f0d0cc3 Use enums to make debugging easier 
When we're dealing with a field which is guaranteed to have an enum type,
then declare it as such so it shows up in debuggers.

b938e043ca phash: don't rely on the build platform Perl version of rand() 
rand() in Perl can vary between platforms, so don't use it.  Instead,
remove a completely pointless level of indirection (it introduced a
permutation which cancelled itself out) and provide a canned set of
random numbers for the rest.  This guarantees we will always use the
same numbers.

91a86cdb31 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().

the same width as the "hash" arrays.

fb5a599c8a 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.

74cc5e569c Finishing touches on perfect hash tokenizer; actually turn the thing on 
Finish the perfect hash tokenizer, and actually enable it.

Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.

Run make alldeps.
