commit fd91891a5091b5f54680180dc0c8e91827f63c70

    Correct "inexact" expectations in lround, llround tests.
    
    I noticed that some of my recently added tests of lround and llround
    wrongly expected the "inexact" exception to be absent for certain
    within-range non-integer arguments.  (It's unspecified whether this
    exception is present or not for within-range non-integer arguments; it
    mustn't be present for integer arguments and out-of-range arguments.)
    This patch corrects those expectations.
    
    Tested for x86_64 and x86.
    
    	* math/libm-test.inc (lround_test_data): Do not expect the absence
    	of "inexact" for some tests with non-integer arguments.
    	(llround_test_data): Likewise.
