Log Message:
lldb-netbsd: Fix AUXV reading; fix setting brakpoint; update TODO

xmm2, ymm0-ymm15 recognizion works; but it's not finished

auxv reading works good enough for now; it might be taylored down later

getthreadname / setthreadname has been... moved to llvm

reading general purpose registers work

setting and detecting breakpoint appear to work, but a trap is not unset
and program is getting corrupted later

TODO on amd64:
 - fix breakpoints
 - FPR registers support
 - debug registers support
