Add new tests dbregs_dr[0123]_trap_code in arch/amd64
Add new tests: - dbregs_dr0_trap_code - dbregs_dr1_trap_code - dbregs_dr2_trap_code - dbregs_dr3_trap_code This is the final set of tests for trap types that are supposed to be supported by all amd64 CPUs. Traps for code (instruction) execution must be set to 1 byte, otherwise they are undefined. x86 code traps must point to the first byte of an instruction. Sponsored by <The NetBSD Foundation>
