Log Message:
Fix and revive test of atan_inf_neg, atan_inf_pos and atan_tan on i386.
PR port-i386/46108.
The machine epsilon 1.0e-40 is too severe and nonsense for double
because DBL_EPSILON is about 2.2e-16 . I think that 1.0e-15 is
enough good, in this case.
XXX However, test of atan_tan should be replaced for other reasons.
