    nptl: Fix cleanups for stack grows up [BZ# 28899]

    _STACK_GROWS_DOWN is defined to 0 when the stack grows up.  The

    code in unwind.c used `#ifdef _STACK_GROWS_DOWN' to selct the

    stack grows down define for FRAME_LEFT.  As a result, the

    _STACK_GROWS_DOWN define was always selected and cleanups were

    incorrectly sequenced when the stack grows up.
