* math/gen-libm-test.pl (parse_args): Handle isinf and isnan as
type-generic.
* math/libm-test.inc: Update comment listing what functions and
macros are tested.
(finite_test): New function.
(isinf_test): Likewise.
(isnan_test): Likewise.
(fpclassify_test): Test subnormal input.
(isfinite_test): Likewise.
(isnormal_test): Likewise.
(main): Call the new functions.
