[BZ #2466]
* math/gen-libm-test.pl (parse_args): Take function name for pretty
output as an argument.
(generate_testfile): Pass it the name given in the START macro.
[BZ #2466]
* math/libm-test.inc (llrint_test, llround_test): Fix last change to
protect large-precision cases with [LDBL_MANT_DIG > 100].
(llrint_test_tonearest, llrint_test_towardzero): Likewise.
(llrint_test_downward, llrint_test_upward): Likewise.
