MIPS64: Implement miscellaneous bit manipulation intrinsics

// java.lang.Double
- doubleToRawLongBits(double)   - longBitsToDouble(long)

// java.lang.Float
- floatToRawIntBits(float)      - intBitsToFloat(int)

// java.lang.Integer
- numberOfLeadingZeros(int)     - reverseBytes(int)
- reverse(int)

// java.lang.Long
- numberOfLeadingZeros(long)    - reverseBytes(long)
- reverse(long)

// java.lang.Short
- reverseBytes(short)
