    [ARM] Update signal handling for ARM. · 6a8061e8

    Update the ARM signal handling to use the generic
    get_signal_to_deliver() implementation.  There is a caveat though -
    ARM has no hardware support for single stepping, and thus needs the
    kernel to help provide this.
    
    We introduce a new ptrace flag for this, PT_SINGLESTEP, which
    indicates to architecture specific code that it should take extra
    actions in the signal handler to set and/or clear breakpoints as
    appropriate.
