	[BZ #15062]
	* math/k_casinh.c (__kernel_casinh): Compute real and imaginary
	parts of result separately when argument is not close to line from
	-i to i and one part of argument is small.
	* math/k_casinhf.c (__kernel_casinhf): Likewise.
	* math/k_casinhl.c (__kernel_casinhl): Likewise.
	* math/libm-test.inc (cacos_test): Add more tests.
	(casin_test): Likewise.
	(casinh_test): Likewise.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
	* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
