* math/atanq.c (atanq): Update from GLIBC. Handle tiny and
very large arguments properly.
* math/j0q.c (y0q): Update from GLIBC. Avoid arithmetic
underflow when 'x' is very small.
* math/j1q.c (y1q): Ditto.
* math/log1pq.c (log1pq): Update from GLIBC. Saturate
nonzero exponents with absolute value below 0x1p-128 to
+/- 0x1p-128.
* math/powq.c (powq): Update from GLIBC. If xm1 is
smaller than LDBL_EPSILON/2.0L, just return xm1.
