[LLDB] Add support for AVR breakpoints 

I believe the actual opcode does not matter because the AVR architecture
is a Harvard architecture that does not support writing to program
memory. Therefore, debuggers and emulators provide hardware breakpoints.
But for some reason, this opcode must be defined or else LLDB will crash
with an assertion error.
