[PATCH 7/8] float128: Add private _Float128 declarations for libm.

[Joseph Myers]

The internal function declarations, hidden_proto calls etc. in this patch 
are another case that would best be macroized with only the macro 
definitions depending on float128 support.  Especially these ones:

> +/* Float128 variants. */
> +#if __USE_FLOAT128
> +extern _Float128 __ieee754_sqrtf128 (_Float128);
> +extern _Float128 __ieee754_acosf128 (_Float128);
[...]

as the largest block of code repeating something done for other types.
