Fix memcmp(3) usage when comparing registers. Comparing with len is
incorrect as it should be len*sizeof(register) or just sizeof(registers).

Don't check for 16 Debug Registers, it's amd64 specific and not portable
to i386.

Don't compare registers before and after triggering a trap, it's a bug that
was hidden by incorrect usage of memcmp(3).
