Add global REAL_VALUE_TYPE infinities to real.*.
We're starting to abuse the infinity endpoints in the frange code and
the associated range operators. Building infinities are rather cheap,
and we could even inline them, but I think it's best to just not
recalculate them all the time.
I see about 20 uses of real_inf in the source code, not including the
backends. And I'm about to add more :).
gcc/ChangeLog:
* emit-rtl.cc (init_emit_once): Initialize dconstinf and
dconstninf.
* real.h: Add dconstinf and dconstninf.
