Implement the MOV instruction for control and debug registers. Remove definitions for non-existant registers CR1, CR4, CR5, CR6 and CR7. The standard 80486 doesn't have a CR4 register (although some implementations of the 80486 had large page support and CR4, it was not reliable). As for the debug registers, DR4 is the same as DR6, and DR5 is the same as DR7. svn path=/branches/ntvdm/; revision=60747
