Also add index entries for 'denormalized value' and 'value,
denormalized', pointing to 'number, subnormal'.

Fixes #1017.

This should probably be reviewed by @zygoloid, in particular whether he wants to go there in the first place.

It seems truly strange to be talking about subnormals here, but not mentioning the possibility of them existing at all, or what they might mean, anywhere within the core language. We don't even have a normative reference to ISO/IEC/IEEE 60559, except perhaps indirectly via ISO/IEC 9899.

But that's all a pre-existing problem. If we're going to have this mess, using the latest 60559 terminology to describe it seems reasonable to me.
