2e7dd975eb Macros for SSSE3/SSE4 instruction sets 
Add instruction set flags for the SSSE3, SSE4.1 and SSE4.2 instruction
subsets.

0da6b580eb Support r/m operands for non-integer types 
Support r/m operands for non-integer operands types, i.e. mmx or xmm
operands.  This allows mmx and xmm operands to be written more
compactly, speeding up the assembler.

16b0a33cea Use enumerations where practical to ease debugging 
We have a lot of enumerations; by declaring fields as such, we make it
easier when debugging, since the debugger can display the enumerations
in cleartext.  However, make sure exceptional values (like -1) are
included in the enumeration, since the compiler otherwise may not
include it in the valid range of the enumeration.

7978feebd2 pptok.c: quick-and-dirty downcasing during prehashing 
Speed up pptok.c by just doing |= 0x20 instead of calling tolower() for
every character during prehashing.  This is good enough for our needs,
since we don't have any tokens containing the characters @ [ \ ] _ nor
any high-bit characters (in which case we'd have to worry about multibyte
anyway.)

Tell the user when the graph is OK, so that we don't get quite so much of
"a list of errors followed by a long pause."

3100e6cb63 pptok.c: handle holes in the pp_directives array 
We need to fail if we land in a hole in the pp_directives array, since
we have a noncontiguous enum preproc_token now.

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.

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().

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.
