Fix debugger only displaying 16 bits of 64-bit integers in the Inspect Memory window

[zhuowei]

The "64-bit integer" display option in Debugger only displays 16 bits of each integer.

Steps to reproduce:

run

Debugger /bin/bash

In the right-pane, select Registers,

right-click rsp and choose Inspect

change Hex Mode to 64-bit

Expected result: the actual values in memory are printed as 64-bit integers

Actual result: only the bottom 16 bits are printed (if in little endian mode) or the top 16 bits (if in big endian mode)

A patch is attached to fix this issue.

Oops, mea culpa. Patch looks good to me in any case, so if anyone wants to apply it immediately they're welcome to, otherwise I'll do so after work tonight.
