Add more libm tests (modf, nearbyint, nextafter, nexttoward, pow, remainder, remquo, rint).

This patch improves the libm test coverage for a few more functions.

Tested for x86_64 and x86.

	* math/libm-test.inc (modf_test_data): Add more tests.
	(nearbyint_test_data): Likewise.
	(nextafter_test_data): Likewise.
	(nexttoward_test_data): Likewise.
	(pow_test_data): Likewise.
	(remainder_test_data): Likewise.
	(remquo_test_data): Likewise.
	(rint_test_data): Likewise.
