/* Percent tokens in strings:
First char after '%':
A - direct address
C - reg of r/m picks control register
D - reg of r/m picks debug register
E - r/m picks operand
F - second operand for mmx instruction reg/mem
G - reg of r/m picks general register
I - immediate data
J - relative IP offset
+ K - call/jmp distance
L - first operand for mmx instruction
M - r/m picks memory
O - no r/m, offset only
R - mod of r/m picks register only
S - reg of r/m picks segment register
T - reg of r/m picks test register
X - DS:ESI
Y - ES:EDI
2 - prefix of two-byte opcode
+ e - put in 'e' if use32 (second char is part of reg name)
+ put in 'w' for use16 or 'd' for use32 (second char is 'w')
+ j - put in 'e' in jcxz if prefix==0x66
f - floating point (second char is esc value)
g - do r/m group 'n', n==0..7
p - prefix
s - size override (second char is a,o)
+ d - put d if double arg, nothing otherwise (pushfd, popfd &c)
+ w - put w if word, d if double arg, nothing otherwise (lodsw/lodsd)
+ P - simple prefix
Second char after '%':
a - two words in memory (BOUND)
b - byte
c - byte or word
d - dword
+ f - far call/jmp
+ n - near call/jmp
p - 32 or 48 bit pointer
+ q - byte/word thingy
s - six byte pseudo-descriptor
v - word or dword
w - word
+ x - sign extended byte
y - qword
F - use floating regs in mod/rm
M - use MMX regs
1-8 - group number, esc value, etc
m - no size memory operand
