[PATCH] Add one test, removed a duplicated one, add a few comments about missing tests.

[Thomas Schwinge <thomas at codesourcery dot com>]

	* math/libm-test.inc (acosh_test): Also test with qNaN input.
	(sqrt_test): Remove duplicate test with qNaN input.
	(lrint_test, llrint_test, lround_test, llround_test, rint_test)
	(round_test, signbit_test, significand_test): Note missing +/-Inf
	as well as qNaN tests.
