Add more tests of lrint, llrint, lround, llround.
This patch adds more tests of lrint, llrint, lround and llround, to cover various standard special cases not previously covered, and more tests of overflow. Tested for x86_64 and x86. * math/libm-test.inc (lrint_test_data): Add more tests. (llrint_test_data): Likewise. (lround_test_data): Likewise. (llround_test_data): Likewise.
