[LLDB] Fix Read/Write memory to be compatible with both endians

[mohit.bhakkad]

Summary

While copying a byte, copy a whole byte chunk instead of each bit, to make it compatible with both endians.

This will be a buffer overrun if "size % sizeof(long) != 0" (and also violating strict aliasing). I suggest to use memcpy instead what fixes both of these issue.

Same here

LGTM

I can't accept it on the UI because of some bug, but you can commit it without waiting for Greg.
