This intrinsic implements IEEE-754 operation roundToIntegralTiesToEven, and performs rounding to the nearest integer value, rounding halfway cases to even. The intrinsic represents the missed case of IEEE-754 rounding operations and now llvm provides full support of the rounding operations defined by the standard.
