math: Use accurate answers for cos and sincos.
Use the most accurate hex literals possible for the answers to the cos and sincos tests that vary according to the error in the rounding of PI/2. --- 2013-04-24 Carlos O'Donell <carlos@redhat.com> * math/libm-test.inc (cos_test): Use accurate hex constants. (sincost_test): Likewise.
