History
Joseph Myers b821f414e4 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.
