Log Message:
-----------
Check that positive subnormals are not constant-folded to zero
If nvtype is either double, DoubleDouble, or 80-bit extended precision long
double, it checks the smallest possible positive value (aka DENORM_MIN). Else,
(IEEE 754 long double or __float128), it checks a subnormal that's larger than
DENORM_MIN. (It could easily be extended to cover DENORM_MIN for all nvtypes.)
