Fix ldbl-128ibm coshl spurious overflows (bug 16407).
This patch fixes bug 16407, spurious overflows from ldbl-128ibm coshl. The implementation assumed that a high part (reinterpreted as an integer) of the absolute value of the argument of 0x408633ce8fb9f87dLL or more meant overflow, but the actual threshold has high part 0x408633ce8fb9f87eLL (and a negative low part). The patch adjusts the threshold accordingly. sinhl probably has the same issue, but I didn't get that far in adding tests of special cases (such as just below and above overflow) before the freeze and during the freeze is not a suitable time to add them (as they'd require ulps to be regenerated again), so I'm not changing that function for now; when I add more tests of special cases, we'll discover whether sinhl indeed has this problem. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/e_coshl.c (__ieee754_coshl): Increase overflow threshold.
