Fix ldbl-128ibm sinhl spurious overflows (bug 19350).
The ldbl-128ibm implementation of sinhl uses a slightly too small overflow threshold (similar to bug 16407 for coshl). This patch fixes it to use a safe threshold (so that values whose high part is above the value compared with definitely result in an overflow in all rounding modes). Tested for powerpc. [BZ #19350] * sysdeps/ieee754/ldbl-128ibm/e_sinhl.c (__ieee754_sinhl): Increase overflow threshold.
