LGTM modulo the test comment.

+ARM64_GPR = [ {'name': 'x0', 'bitsize': 64, 'offset': 0, 'encoding': 'uint', 'format': 'hex', 'set': 0, 'gcc': 0, 'dwarf': 0, 'generic': 'arg0', 'alt-name': 'arg0'},

----------------
Generally constants go at the top of the file, but this is rather bulky, so I don't mind it being at the bottom.

So when I try to emulate the core file process from a Scripted Process, the scripted process never stops because none of its threads has a stop reason. That's why we have to fake a SIGTRAP for x86_64.
That sounds like something worth mentioning as a comment in the test.
