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 Reviewed by: Hal Finkel llvm-svn: 175283

[SelectionDAG] Allow sin/cos -> sincos optimization on GNU triples w/ just -fno-math-errno Summary: This change enables the sin(x) cos(x) -> sincos(x) optimization on GNU target triples. This optimization was being inhibited when -ffast-math wasn't set because sincos in GLibC does not set errno, while sin and cos do. However, this optimization will only run if the attributes on the sin/cos calls include readnone, which is how clang represents the fact that it doesn't care about the errno values set by these functions (via the -fno-math-errno flag).
