  1. hal/ia32: Rename dr4 and dr5 to dr6 and dr7 

    Debug registers DR4 and DR5 are reserved when debug extensions are
enabled (when the DE flag in control register CR4 is set) and attempts
to reference the DR4 and DR5 registers cause invalid-opcode exceptions
(#UD). When debug extensions are not enabled (the DE flag is clear),
these registers are aliased to debug registers DR6 and DR7
