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.
