When bit 29 is set in Test Control MSR register 0x33, a #AC execption
is generated for split locked accesses at all CPL irrespective of
CR0.AM or EFLAGS.AC.
This feature can help developers to capture memory accesses that across cachelines with #LOCK assertion. Then developers can reconstruct their program accordingly
