- 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 Reviewed by: Hal Finkel git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175283 91177308-0d34-0410-b5e6-96231b3b80d8
