        Description

        FLOATPRESSURE represents float LRG's number that constitutes high register pressure.
        On aarch64, current value is 64.
        Decrease its value to 32 because there are 32 float/SIMD registers on aarch64 and also the value of register pressure is the same as 1 for each LRG of Op_RegL/Op_RegD/Op_Vec.
