For x87 extended precision, we want to make a NaN, not a pseudo-NaN. Maybe we should expose the ability to make pseudo-NaNs?

Integer bit is explicit in this format. Intel hardware (387 and later) does not support these bit patterns: exponent = all 1's, integer bit 0, significand 0 ("pseudoinfinity") exponent = all 1's, integer bit 0, significand nonzero ("pseudoNaN") exponent = 0, integer bit 1 ("pseudodenormal") exponent!=0 nor all 1's, integer bit 0 ("unnormal") At the moment, the first two are treated as NaNs, the second two as Normal.
