PPC/s390: [simulator] Add a new command to the debugger to dump memory.

Port 820faa6e707e1059da3caaa0cf3b29fbdf29b173

Original Commit Message:

    The arm/arm64 simulators debugger has a command "mem" that prints
    the content of the memory. It also prints a short summary for JS
    objects (SMI, Array, JSFunction, ...). That is very handy, but
    when trying to print incomplete initialized memory, it could raise
    an exception.

    It is useful to have a command that prints the content of the memory
    for non-initialized or bogus values without the risk of raising
    an exception. This CL adds the command "dump".
