infix fun shr(bitCount: Int): Long
Shifts this value right by the bitCount number of bits, filling the leftmost bits with copies of the sign bit.
Note that only the six lowest-order bits of the bitCount are used as the shift distance. The shift distance actually used is therefore always in the range 0..63.
