enable SDISel sincos optimization for GNU environments
- add sincos to runtime library if target triple environment is GNU
- added canCombineSinCosLibcall() which checks that sincos is in the RTL and
if the environment is GNU then unsafe fpmath is enabled (required to
preserve errno)
- extended sincos-opt lit test
