annamthomas 54a9f0007c [SCEV] Fix BinomialCoefficient Iteration to fit in W bits (#88010) ...

BinomialCoefficient computes the value of W-bit IV at iteration It of a loop. When W is 1, we can call multiplicative inverse on 0 which triggers an assert since 1b76120.
    
Since the arithmetic is supposed to wrap if It or K does not fit in W bits, do the truncation into W bits after we do the shift.
    
 Fixes #87798
