mips.c (epilogue_reg_mentioned_p): Delete unused function.

        * mips.c (epilogue_reg_mentioned_p): Delete unused function.
        (mips_epilogue_delay_slots): Likewise.
        (function_epilogue): Greatly simplify.
        (mips_expand_epilogue): If we have a null prologue/epilogue,
        then use a normal return insn.  Emit blockage insns before
        stack pointer adjustments.
        (mips_can_use_return_insn): Renamed from simple_epilogue_p.  All
        callers changed.  Do not use return insns if $31 is live in the
        function or if generating profiling information.
        * mips.h (DELAY_SLOTS_FOR_EPILOGUE): Delete.
        (ELIGIBLE_FOR_EPILOGUE_DELAY): Likewise.
        * mips.md (return): Remove expander and change the pattern to
        look like a standard "return" insn.
        (return_internal): Show use of $31 explictly.
        (epilogue expander): Enable.
