Fix Float/Double .nextUp/.nextDown on arm(v7). On armv7, leastNonzeroMagnitude is defined to be leastNormalMagnitude. This seems wrong to me from a language point of view, because it's possible to have a nonzero float that compares less than the leastNonzero float. However, it must have been done to gloss over hardware rounding errors. This is not a problem on arm64. As a result, nextUp/Down methods were not self-consistent. I fixed this by skipping over subnormal representations, following the precedent set by leastNonZeroMagnitude. This fixes the FloatingPoint floatNextUpDownTests on armv7.
