When single stepping the asm instructions, I find lldb very slow when
encountering a (large) rep stosb.
The debugger essentially hung.
While I can use Ctrl-C to break the program into debugger, I still can't
continue debugging, because even I put a breakpoint on the next instruction,
and use the "c" command, it is still very slow.
However, if I don't try to single step the rep instruction, and directly put a
breakpoint on the next instruction and use "c", it's way faster.
