[GDB] Zero-extend 16-bit segment registers
When the 16-bit segment registers are accessed using 32-bit instructions
the high order bytes are undefined on older CPUs. We now explicitly
zero the high order bytes when snapshotting the CPU state. This ensures
that the GDB stub reports consistent values for the segment registers.
