Fix for bz#13658 - using fsincos on x86-64


We should not use the inaccurate fsincos instruction on x86-64 (see bugzilla and the discussion on the gcc mailing list). Let's just remove the double version and use the IBM libm sincos implementation.

Unfortunately the same fix does not work for the long double version - since there's no sincos implementation for ldbl-96 yet ;-(. Jakub, you wrote the ldb-128 versions - do you have any suggestions?
