Fix long double on x86_64-windows

The larger alignment on this platform means that long double reports a sizeof 16 bytes, but it's underlying size is really just the 10 bytes of `f80` C doesn't give us a way to see the "underlying" size of a type, so this has to be caught by hand or by monitoring runtime memory. Luckily, x86 and x86-64 are the only platforms that seem to use a non-power-of-two type like this.
