Test drem and pow10 in libm-test.inc

["Joseph S. Myers" <joseph at codesourcery dot com>]

Now that the same test data in libm-test.inc can be used to test
multiple functions, this patch arranges for the drem and pow10
function names (wrapper for remainder, and alias for exp10) to be
tested with the same data as the functions they alias, further
reducing the set of untested libm functions.

Tested x86_64 and x86 and ulps updated accordingly.

2013-05-24  Joseph Myers  <joseph@codesourcery.com>

	* math/libm-test.inc: Add drem and pow10 to list of tested
	functions.
	(pow10_test): New function.
	(drem_test): Likewise.
	(drem_test_tonearest): Likewise.
	(drem_test_towardzero): Likewise.
	(drem_test_downward): Likewise.
	(drem_test_upward): Likewise.
	(main): Call the new functions.
