Description Dominic Szablewski 2013-01-05 09:01:27 PST 
When running JSC in a process without support for denormal numbers (default on iOS6) Number.MIN_VALUE gets round down to 0, which is not very helpful.

If denormal numbers are supported MIN_VALUE should return 5E-324, or 2.2250738585072014E-308 (DBL_MIN) otherwise.

I think std::numeric_limits<double>::denorm_min() would be better here.
