[Cfp-interest 1674] Overflow and HUGE_VAL

[Fred J. Tydeman]

Currently, WG14 N2478  7.12.1#5 has:

If a floating result overflows and default rounding is in effect, then the
function returns the value of the macro HUGE_VAL, HUGE_VALF, or HUGE_VALL according to the
return type, ...

But, since we have added decimal floating-point, do we need to add

HUGE_VAL_D32, HUGE_VAL_D64, HUGE_VAL_D128

or reword?

In addition, 7.22.1.6 The strtodN functions 
are missing HUGE_VAL_Dn in the returns.

Also, 7.29.4.1.2 The wcstodN functions
are also missing HUGE_VAL_Dn in the returns.

And HUGE_VAL_Dn are missing from Annex B.11
