    xtensa: Simplify "*masktrue_const_bitcmpl" insn pattern
    
    gcc/ChangeLog:
    
            * config/xtensa/xtensa.md
            (The auxiliary define_split for *masktrue_const_bitcmpl):
            Use a more concise function call, i.e.,
            (1 << GET_MODE_BITSIZE (mode)) - 1 is equivalent to
            GET_MODE_MASK (mode).
