Eugene Korenevsky 6cd44b0be5 x86_emulate: fix EFLAGS setting of CMPXCHG emulation ...

CMPXCHG sets CF, PF, AF, SF, and OF flags according to the results of the
comparison the rAX with the operand of the instruction.
rAX must be the first argument of the comparison (a minuend), the operand
must be the second one (a subtrahend).

Due to improper order of comparison arguments, CF, PF, AF, SF and OF flags were
set incorrectly in the case of inequality. Need to swap them.

test_x86_emulate: extend EFLAGS check of CMPXCHG test

CMPXCHG: in the case of inequality of the rAX and the operand,
need to check CF, PF, AF, SF and OF flags as well.

This adjustment covers the fix of incorrect comparison during
CMPXCHG emulation.
