Add more libm tests (fmod, fpclassify, frexp, hypot, ilogb, j0, j1, jn, log, log10, log2).

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

Tested for x86_64 and x86.

2015-10-21  Joseph Myers  <joseph@codesourcery.com>

	* math/auto-libm-test-in: Add more tests of hypot, j0, j1, jn,
	log, log10 and log2.
	* math/auto-libm-test-out: Regenerated.
	* math/libm-test.inc (fmod_test_data): Add more tests.
	(fpclassify_test_data): Likewise.
	(frexp_test_data): Likewise.
	(hypot_test_data): Likewise.
	(ilogb_test_data): Likewise.
