/* NOTES BY HERMES:

LZ flag: original opcodes andf and andcf are swaped. Also "jzr" and "jnz" are swaped but now named 'jlz' and 'jlnz' 
As you can see it obtain the same result but now LZ=1 correctly

Added conditional instructions:

conditional names:

NZ -> NOT ZERO
Z  -> ZERO 

NS -> NOT SIGN
S  ->  SIGN

LZ  -> LOGIC ZERO (only used with andcf-andf instructions?)
LNZ -> LOGIC NOT ZERO

G -> GREATER
LE-> LESS EQUAL

GE-> GREATER EQUAL
L -> LESS

Examples:

jnz, ifs, retlnz
