072771e4a5 Use hash tables even for context-sensitive macros 
Normally, contexts aren't used with a large number of macros, but in
case someone does, do use hash tables for those as well.  This
simplifies the code somewhat, since *all* handling of macros is now
done via hash tables.

Future note: consider if it wouldn't be better to allow struct
hash_table to be allocated by the caller, instead of being allocated
by the hash table routine.

bd420c7095 Add tokens vex.ww and vex.wx; vex.wx is the default 
Add vex.ww (for VEX.W follows REX.W) and vex.wx (for VEX.W is a don't
care); vex.wx is the default since that seems to match existing usage
better.

2637aca805 insns.pl: error if we have a 'v' operand and no vex.nds/ndd 
Although redundant, the presence of a 'v' operand should match the
existence of a nds or ndd flag on vex; this should help catch typos.

a69ce1d19d insnsn.c: cleaner to *not* separate out conditional instructions 
The disassembler code gets cleaner if we do *not* separate out the
conditional instructions; instead, rely on the fact that the
conditionals are always at the end and use FIRST_COND_OPCODE as a
barrier.

2fb033af18 Disassembler: select table based on VEX prefixes 
We can use the new VEX prefixes to select into a large table of new
opcode spaces.  Since the table is (currently) sparse, add logic so we
don't end up producing tons of empty tables for no good reason.

This is also necessary since VEX is likely to reuse opcode bytes that
would appear as prefixes at some point, which would cause conflicts
with the regular tables.

eb9e093840 Fix skipping 0270 code when searching for disasm prefixes 
The 0270 code was incorrectly entered as 270 (decimal), which meant
that instructions with vex but no .nds got misfiled in the improper
opcode tables.

39d6ac6f79 Fix display for fixed xmm0/ymm0, SSE redundant prefixes 
All singleton registers need to be displayable from register flags
alone!

When using the new 0360..0363 codes, make sure we appropriate avoid
displaying the legacy use of the prefixes.

76ec8e73db Fix buffer overflow in preproc.c (BR 1942146) 
Fix buffer overflow in preproc.c due to an incorrect test.  In the
code:

        for (r = p, s = ourcopy; *r; r++) {
	    if (r >= p+MAX_KEYWORD)
	    	return tokval->t_type = TOKEN_ID; /* Not a keyword */
            *s++ = tolower(*r);
	    }
        *s = '\0';

... the test really needs to be >= since for the pass where there are
equal:

a) a nonzero byte means we have > MAX_KEYWORD characters, and
b) s = ourcopy+MAX_KEYWORD; but if the test doesn't trigger,
   we can write one more character *plus* the null byte, overflowing
   ourcopy.
