Jeff Johnston 31cf34f849 or1k: Allow exception nesting 
Allow exceptions to be nested, which is especially useful with urgent
    interrupts while processing an exception.

    The implementation counts up the nesting level with each call to an
    exception. In the outer exception (level 1), the exception stack is
    started. All nested exceptions just reserve the redzone (scratch
    memory that may be used by compiler) and exception context on the
    stack, but then process on the same scratch.

    Restriction: Impure pointers are shared among all exceptions. This may
    be solved by creating an impure data structure in the stack frame with
    each nested exception.

       * or1k/crt0.S: Add exception nesting
       * or1k/exceptions-asm.S: ditto
       * or1k/util.c: ditto
