	* math/libm-test.inc (lrint_test): Add new test.
	(llrint_test, lround_test, llround_test): Likewise.
	* sysdeps/ieee754/ldbl-128/s_lroundl.c (__lroundl): Fix special case
	with result taking up 48 bits.
	* sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Likewise.
	* sysdeps/ieee754/ldbl-128/s_llroundl.c (__llroundl): Likewise.
	* sysdeps/ieee754/ldbl-96/s_llrintl.c (__llrintl): Fix special case
	with result taking up 31 bits.
