Stop raising OverflowError on underflows reported by libm (errno==ERANGE and libm result is 0). Cautiously add a few libm exception test cases: 1. That exp(-huge) returns 0 without exception. 2. That exp(+huge) triggers OverflowError. 3. That sqrt(-1) raises ValueError specifically (apparently under glibc linked with -lieee, it was raising OverflowError due to an accident of the way mathmodule.c's CHECK() macro happened to deal with Infs and NaNs under gcc).
