[TOKENIZER] Modifiers handling is unfinished

[pablo-lamtenzan]

Modifiers (operand READ | WRITE, affected flags) are handled but only for unprefixed instructions which resolution is performed directly through the lookup table.
The same work must be done (create and fill lookup tables) for the 0x0F, 0x0F38 and 0x0F3A prefixes.
Also for indexing, extensions, addons, overwrittings, ...

NOTE: Maybe the kind of affected flags varies across the processor extensions. This may lead to more issues.
