Ensure isinff, isinfl, isnanf, and isnanl are defined (Bug 19439)

Browse Source 
In ICO C++11 mode ensure that isinff, isinfl, isnanf, and isnanl
are defined.  These functions were accidentally removed from the
header as part of commit d9b965fa56,
but being GNU extensions, they should have been left in place.
