target-i386: fix cmpxchg instruction emulation
When the i386 cmpxchg instruction is executed with a memory operand and the comparison result is "unequal", do the memory write before changing the accumulator instead of the other way around, because otherwise the new accumulator value will incorrectly be used in the comparison when the instruction is restarted after a page fault. This bug was originally reported on 2010-04-25 as https://bugs.launchpad.net/qemu/+bug/569760 Signed-off-by: Andreas Gustafsson <gson@gson.org>
