Great! Just tested it, everything seems to be working fine in Debugger now.
There's still the TODO for ArchitectureX8664::CreateStackFrame that's
getting hit when the unwind reaches _start, so I'll try implementing that
at some point (even though it'll only work with -fno-omit-frame-pointer),
and there's a couple of other TODOs I put in that I need to look at.
Thanks,
