Add more libm tests (ilogb, is*, j0, j1, jn, lgamma, log*).

This patch improves the libm test coverage for a few more functions.

Tested for x86_64 and x86.

	* math/auto-libm-test-in: Add more tests of log, log10, log1p and
	log2.
	* math/auto-libm-test-out: Regenerated.
	* math/libm-test.inc (MAX_EXP): New macro.
	(ilogb_test_data): Add more tests.
	(isfinite_test_data): Likewise.
	(isgreater_test_data): Likewise.
	(isgreaterequal_test_data): Likewise.
	(isinf_test_data): Likewise.
	(isless_test_data): Likewise.
	(islessequal_test_data): Likewise.
	(islessgreater_test_data): Likewise.
	(isnan_test_data): Likewise.
	(isnormal_test_data): Likewise.
	(issignaling_test_data): Likewise.
	(isunordered_test_data): Likewise.
	(j0_test_data): Likewise.
	(j1_test_data): Likewise.
	(jn_test_data): Likewise.
	(lgamma_test_data): Likewise.
	(log_test_data): Likewise.
	(log10_test_data): Likewise.
	(log1p_test_data): Likewise.
