- Fix the privilege checks.
- Store the CPL in a special field, so that it doesn't get mixed up
with the lowest 2 bits of real mode selectors while switching
into protected mode.
- Reset the exception count after a successful ISR call.
- In Fast486OpcodeGroup0F01, check for prefix overrides after parsing
the Mod-Reg-R/M, which might add a SS: prefix override in some cases.

Fix the calculation of MaxValue by using SignFlag | (SignFlag - 1) instead.
