The round-to-nearest-even implementation found in lower_2f() is incorrect
for any value having a significand that is not directly representable
and whose non-representable part lies between 1 and half the minimum
representable value. In this case, the significand is rounded up instead
of being rounded down.
Fixes: 936c58c8fc ("nir: Extend nir_lower_int64() to support i2f/f2i lowering")
