/** \brief
* This is a helper function that will try to use a rotate instruction
* to perform an 'land' (Long AND) operation. It will handle cases
* where the second child of the Long AND is a lconst node, and the
* lconst value is a sequence of contiguous 1's surrounded by 0's or vice versa.
* For example, the lconst value can be:
* 00011111111000, 1111000000011111, 0100000
*
* For example, consider the following tree:
*
* land
* i2l
* iload parm=0
* lconst 0x0000FFFFFFFF0000
*
* We can either materialize the constant in a register or use the NIHF+NILF instructions
* to AND the most and least significant 32 bit portions in the first operand. These
* are both more expensive than generating a RISBG instruction.
*
* This is because in the above case we can perform the AND operation with the
* following single RISBG instruction:
*
* RISBG R2,R1,33,175,0 //R1 holds parm 0
*
* In the above instruction the value of 175 comes from
* the sum of 128 and 47. 47 represents the ending position
* of the bit range to preserve, and 128 is there to set the
* zero bit. The instruction is saying to take the value in R1 and
* do the following:
* -preserve the bits from 33 - 47 (inclusive)
* -zero the remaining bits
* -rotate the preserved bits by a factor of 0(hence no rotation)
* -store the result in R2
*
* Note: RISBG is non-destructive (unlike the AND immediate instructions).
* So the original value in R1 is preserved.
*
* \param node
* The land node
*
* \param cg
* The code generator used to generate the instructions
*
* \param shiftAmount
* The number of bits we should shift the result of the logical AND. A positive value represents a left shift,
* a negative value represents a right shift, and a value of zero represents no shift.
* Note that if the absolute value of number is greater than 6 bits, then this optimization will not work
* since the RISBG instruction will only hold 6 bits for the shift operand.
*
* \param isSignedShift
* If replacing a signed shift+and combination, this variable evaluates to true. Else it will evaluate to false.
* Note: If we are using this function to replace a standalone 'and', then this variable should be false.
*
* \return
* The target register for the instruction, or NULL if generating a
* RISBG instruction is not suitable
*
