Move tests of catan, catanh to auto-libm-test-*.

This patch moves tests of catan and catanh with finite inputs (other
than the divide-by-zero cases producing an exact infinity) to using
the auto-libm-test machinery.  Each of auto-libm-test-out-catan and
auto-libm-test-out-catanh takes about three seconds to generate on my
system (so in fact it wasn't necessary after all to defer the move to
auto-libm-test-* until the output files were split up by function).

Tested for x86_64 and x86 and ulps updated accordingly.

	* math/auto-libm-test-in: Add tests of catan and catanh.
	* math/auto-libm-test-out-catan: New generated file.
	* math/auto-libm-test-out-catanh: Likewise.
	* math/libm-test-catan.inc (catan_test_data): Use AUTO_TESTS_c_c.
	Move tests with finite inputs, except divide-by-zero cases, to
	auto-libm-test-in.
	* math/libm-test-catanh.inc (catanh_test_data): Likewise.
	* math/Makefile (libm-test-funcs-auto): Add catan and catanh.
	(libm-test-funcs-noauto): Remove catan and catanh.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
	* sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise.
	* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
