    sim: mloop: mark a few conditionally used funcs as unused
    
    These are marked inline, so building w/gcc at higher optimization
    levels will automatically discard them.  But building with -O0 will
    trigger unused function warnings, so fix that.
    
    The common before/after cover functions in the common mloop generator
    are not used by all architecture ports.  Doesn't seem to be a hard
    requirement, so marking them optional (i.e. unused) is fine.
    
    The cris execute function is conditionally used depending on the
    fast-build mode settings, so mark it unused too.
