Sanjay Patel 160a5b1a73 [DAG] Remove redundant FMUL in Newton-Raphson SQRT code ... When calculating a square root using Newton-Raphson with two constants, a naive implementation is to use five multiplications (four muls to calculate reciprocal square root and another one to calculate the square root itself). However, after some reassociation and CSE the same result can be obtained with only four multiplications. Unfortunately, there's no reliable way to do such a reassociation in the back-end. So, the patch modifies NR code itself so that it directly builds optimal code for SQRT and doesn't rely on any further reassociation. Patch by Nikolai Bozhenov!
