Add more libm tests (fabs, fdim, fma, fmax, fmin, fmod).

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

Tested for x86_64 and x86.

	* math/libm-test.inc (fabs_test_data): Add more tests.
	(fdim_test_data): Likewise.
	(fma_test_data): Likewise.
	(fmax_test_data): Likewise.
	(fmin_test_data): Likewise.
	(fmod_test_data): Likewise.
