Stanislav Shwartsman d4688e8b95 - Do not compile support for alignment check (#AC exception) by default 
for CPU emulation performance reasons, the alignment check compilation
    still can be enabled using configure option --enable-alignment-check.

There is no software in the world which enable #AC exception checking, this
x86 feature is completely legacy but its emulation support costs up to 3-5%
emulation speed.

The checking for #AC exception enable still will be done, if

 CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1

but the alignment check is not compiled in, the Bochs will PANIC with corresponding message.
You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.
