add or1knd (no delay slot) version.
this is controlled by turning on the ND bit (0x400) in the cpu.cfg configuration variable.

* ChangeLog

2012-10-28  Peter Gavin  <pgavin@gmail.com>

        add or1knd (no-delay slot) target
        * sim-nd.cfg: new file: configuration for no-delay target.
        essentially a copy of sim.cfg.
        * Makefile.am:
        (DISTCHECK_CONFIGURE_FLAGS) use $(target_alias) instead of or1k-elf
        (EXTRA_DIST) add sim-nd.cfg
        * config.sub: add or1knd target
        * config.guess: ditto
        * configure.ac: ditto
        * cpu/or1k/spr-defs.h:
        (SPR_CPUCFGR_ND) no-delay slot flag
        * cpu-config.c:
        (cpu_cfgr) allow SPR_CPUCFGR_ND bit to be set in the argument
        * cpu/or32/insnset.c:
        (l_j) check if ND bit is set; if so, don't use delay slot. this is
        done by setting pcnext directly, and *not* setting next_delay_insn
        or cpu_state.pc_delay, which are ignored altogether in nodelay mode.
        (l_jal) ditto
        (l_jr) ditto
        (l_jalr) ditto
        (l_bf) ditto
        (l_bnf) ditto

* testsuite/ChangeLog:

2012-10-28  Peter Gavin  <pgavin@gmail.com>

        add nodelay target
        * lib/libsim.exp: check target, and choose or1k or or1knd config
        files as appropriate
        * lib/or1ksim.exp: ditto
        * libsim.tests/cfg/*: moved to libsim.tests/cfg/or1k/
        * libsim.tests/cfg/or1knd/default.cfg: new file, copied from or1k
        version and cfgr bit for nodelay turned on
        * libsim.tests/cfg/or1knd/int-edge.cfg: ditto
        * libsim.tests/cfg/or1knd/int-level.cfg: ditto
        * libsim.tests/cfg/or1knd/upcalls.cfg: ditto
        * or1ksim.tests/cfg/*: moved to or1ksim.tests/cfg/or1k/
        * or1ksim.tests/cfg.exp: add nodelay testcase
        * or1ksim.tests/cfg/or1knd/default.cfg: new file, copied from or1k
        version and cfgr bit for nodelay turned on

        * or1ksim.tests/cfg/or1knd/pcu.cfg: ditto
        * or1ksim.tests/inst-set-test.exp: change addresses in testcases
        to offsets so that the output is position independent; this way
        the output identical in nodelay mode
        * or1ksim.tests/int-test.exp: add nodelay test case

* testsuite/test-code-or1k/ChangeLog:

2012-10-28  Peter Gavin  <pgavin@gmail.com>

        output from test, so that it is position independent, and will
        work whether nodelay is on or off
        * cache/cache.c:
        (jump_and_link) don't emit l.nop after l.jr when in nodelay mode
