    xtensa: Remove an unnecessary constraint modifier from movsf_internal insn pattern
    
    In this case, there is no need to consider reloading when memory is the
    destination.  On the other hand, when memory is the source, reloading
    read from constant pool becomes double indirection and should obviously
    be avoided.
    
    gcc/ChangeLog:
    
            * config/xtensa/xtensa.md (movsf_internal):
            Remove destination side constraint modifier '^' in the third
            alternative.
