Cast registers to unsigned in get_register
Cast registers to unsigned in get_register

GDB types registers, meaning $esp and $eax, for example, can have the
same value, but evaluate to different values (eax being negative, esp
always unsigned). This casts the value to an unsigned.

This fixes DereferenceCommand not showing when other registers point to
an address.
