Move tests of casin, casinh to auto-libm-test-*.

Move tests of casin, casinh to auto-libm-test-*.

This patch moves tests of casin and casinh with finite inputs to using
the auto-libm-test machinery.  Each of auto-libm-test-out-casin and
auto-libm-test-out-casinh takes about 38 minutes to generate on my
system because of MPC slowness on special cases that appear in the
tests (with MPC 1.0.3; I don't know to what extent current MPC master
might speed it up).

Tested for x86_64 and x86 and ulps updated accordingly.

	* math/auto-libm-test-in: Add tests of casin and casinh.
	* math/auto-libm-test-out-casin: New generated file.
	* math/auto-libm-test-out-casinh: Likewise.
	* math/libm-test-casin.inc (casin_test_data): Use AUTO_TESTS_c_c.
	Move tests with finite inputs to auto-libm-test-in.
	* math/libm-test-casinh.inc (casinh_test_data): Likewise.
	* math/Makefile (libm-test-funcs-auto): Add casin and casinh.
	(libm-test-funcs-noauto): Remove casin and casinh.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
	* sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise.
	* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
