This patch is a small commit to add a debug register group, and control 
and status register aliases. In the hardware documentation the 
terminology refers to debug control and debug status registers. These 
correspond to D6 and D7 in IA32, and DR6 and DR7 in X8664. These aliases 
are no more than a convenience to allow the programmer to refer to the 
registers by name as they are referred to in the AMD and INTEL 
documentation. The debug groups are just convenient ways to access the 
debug registers as part of a group, distinct from other registers.
