re PR c/86420 (nextafter(0x1p-1022,0) is constant folded)
PR c/86420
* real.c (real_nextafter): Return true if result is denormal.
* gcc.dg/nextafter-1.c (TEST): Adjust the tests that expect denormals
to be returned and when first argument is not 0, so that they don't do
anything for NEED_EXC or NEED_ERRNO.
